Initiating fusions

Many fusions happen spontaneously in the course of treatment. If your mind naturally leans toward singularity, you may eventually reach final fusion simply by working through trauma and building system cooperation. But if you want final fusion or fusion with a particular alter / part, there are ways to support that process. The most important thing is to never try to force a fusion. Premature fusion can negatively affect your mental health and quite often falls apart sooner or later, which will only discourage you from trying again. Don’t give in to pressure from others or from yourselves to achieve it as quickly as possible. This process takes time.

It’s also worth having realistic expectations about fusion so you don’t end up disappointed. It’s not always an entirely positive experience – you may need to grieve lost in-system relationships or lost abilities.^[1] Final fusion is also usually not the end of treatment^[2] – there will still be a lot to work through, along with learning how to function in the world as a singlet, without dissociative mechanisms. Additionally, some headmates may see fusion as the only way to escape their suffering. That in itself isn’t a contraindication, since fusion often helps in coping with pain, but it’s important to keep in mind that in most cases it won’t solve everything, and the newly formed person will still need to process trauma and all the difficult emotions tied to it. In such situations, it’s worth considering whether this is a genuine desire for fusion or disguised suicidal ideation – in the latter case, it’s better to look for another way that allows this headmate to live without suffering, while still remaining themselves.

We assume you’ve already at least started developing system communication and cooperation, since those are the foundation for achieving any kind of fusion.

Getting to know each other

Getting to know each other better is a good way to lower amnesia barriers. This may be because when you can predict what a given person will think in a specific situation, it becomes easier to pick up on those thoughts. Or it may come from growing trust, which makes you stop subconsciously hiding thoughts and memories from each other. Either way, this is where you should start (as long as you already have the basics of healthy coping mechanisms in place). A good idea is to spend as much time together as possible – for example by planning with a specific headmate shared fronting activities that you both enjoy, or by holding regular meetings in the innerworld. If talking to each other doesn’t come naturally, you can use the same methods as when getting to know external people: asking questions like “what do you like the most?” or “what are your dreams?”, or playing social games that help people bond (e.g. never have I ever, would you rather). It’s important not to say anything by force if you’re not ready to share something yet, and especially not to force contact on headmates who aren’t ready for it. First of all, trust and bonds take time to form, and second – amnesia barriers exist for a reason, and if you try to lower them too early, you may uncover memories that some of you aren’t ready to handle yet.

Finding similarities

If you’re aiming for partial or final fusion, it’s best to start by looking for headmates who are similar to each other in terms of their role, personality, or desires. These kinds of fusions often happen naturally, so you can use that to your advantage. It may help to create a system map, for example based on roles or split history (headmates who split from each other recently may have more motivation, and therefore an easier time merging back together). Then you can pair up or form small groups based on how close you are on that map, and work toward merging within those groups (and then regroup again based on similarities, continuing until you reach your desired system size).

When aiming for individual fusions, keep focusing on shared traits. If you want to become one person, you don’t want to be in constant conflict with each other, so it’s best to focus on your shared goals and the ways you want to achieve them. The simplest goal most of you likely share is survival, and beyond that it can be anything that matters to you – from family life and work, to collecting mugs or winning a LOL tournament. Working out compromises in areas where you disagree becomes easier when you know you’re on the same team. And the closer you grow to each other, the easier it becomes to accept even the things you don’t understand and currently see as a waste of time – if not because the boundaries between you start to blur, then because they matter to someone who is becoming important to you. Don’t treat fusion as just a box to check – think about what comes after as well. You don’t want to end up as a person who hates themselves or who they used to be.

Sharing memories

Sharing memories, not just traumatic ones, can help lower amnesia barriers, which is a necessary step on the path to fusion. Even in non-amnesiac systems, showing your perspective and the emotions tied to a specific event can help bring you closer together. The important thing is to do this while you’re in a stable state, because for many of you this may involve uncovering traumatic memories, and approaching this stage too early can put you at serious risk. You can start with simply talking about what happened or writing events down in a journal, but you should aim for more than that. You want to be able to share access to these memories so that the other person remembers them as their own. Various visualization / self-hypnosis techniques may be helpful here. For example, you can imagine physically handing a memory to another headmate in the form of a 3D movie or colorful orbs inspired by “Inside Out”.

Self-hypnosis

On top of the previous techniques you may try convincing your subconscious that you are already one person – of course only when you’re ready, since trying too early may not work or could even be harmful. In many systems, when two headmates are ready for fusion, simply making this decision and combining it with an innerworld action is enough. The action is often something like hugging and then physically merging together.

If that doesn’t help, you can try nudging your brain in the right direction (which may also give you more control over who you become after fusion, since usually you’re at the mercy of subconscious processes). The idea is to act as one person until it becomes your reality. If possible, spend all your time together and don’t front separately. If you have that level of control over your innerworld, you can create a single body, start using it in interactions with the rest of the system, and live in one shared room or house. If you use a bot like Pluralkit, you can start posting with the same proxy. You may ask others to address you by one chosen name and start speaking and thinking in “I” instead of “we” – let every experience, emotion, relationship, and memory of the other alter become yours as well. With time, this way of functioning may start to feel more and more natural, until eventually your subconscious – and you yourselves – will begin to perceive you as one whole. But it’s important to step back to earlier stages if you feel that these actions are harming you – that’s most likely a sign that it’s still too early.
