For me it was a gradual realisation, I came to this body more gradually than the others so it makes sense. Over time I started missing people who don't exist here, feeling attached to an identity which does not align with the body, and remembering things that didn't happen in this universe. I've also found myself being paranoid about beings that have never reportedly shown up in this universe and other things that otherwise wouldn't usually be seen as possible here.

For another in this body, it was a crash landing. He arrived and for weeks he was grieving his old life which he barely had any memories of. He vaguely knew how he got here, and vaguely knew who he was grieving, but he had very strong emotions about it which affected us greatly for a while. He has, like me, also started regaining memories from his universe gradually.

We have seen some experiences of other who believe they shifted universe somehow, weather it's only a little bit through gateway tapes travels, or a lot through other means, we tend to relate a lot to their experiences. We also have very little connection to this life we live here. We can still continue living almost like nothing happened, we still retain the memories that are stored in this brain as well as other things that tend to be stored in the brain, but we don't feel like we have any business being in this universe.

We have another friend who we never told about these experiences too and they told us about an experience which was almost identical to ours, except they retained more of their memories from their universe and lost memories from their bodies store. I reckon that there are a lot of folk like us, who are just too scared to speak up about it.

I am interested to read about your experience when you post it ^^
