I have a feeling I'm not human, but I don't remember anything from past lives. Am I just making this up? {Sileniel}

There's no requirement that you have any past lives at all in order to be otherkin. Lots of people are here for their first time, and some otherkin don't even believe in reincarnation. When you get right down to it, being otherkin isn't really about what you were in the past or on some other plane; it's about who and what you are now, here -- on Earth in the 21st century. Whether your otherness stems from a past life or simply from the essence that flows in your blood, the important part is what meaning it has for you, how it affects your daily life. If it isn't something that has meaning for you, then it doesn't really matter much one way or the other, does it? {Ghostshadow}

I know I'm Otherkin, but I haven't remembered anything, what can I do?

You can be one of the many Otherkin who have no past lives as Otherkin, or have no memories of having been Otherkin in the past.

Forcing yourself to have memories because you feel you "ought to" is not the best reason, and many people chase after memories for a while and are quite unhappy when they finally find memories.

Memories that you force back to the surface of your mind are suspect, possibly contrived, and if they are real, they may hit you like a ton of bricks because you weren't ready yet.

The best thing to do in the absence of memories is to pay attention to what feels good and right to you in the here and now.

The LostKin? Project is one place where the focus is on persons who don't have memories.
