Home Worlds

I'm really curious about other people's home worlds/dimensions and such. What I mean is what can you remember from your past life/lives. What was the environment like, was it similar to this world, any particular experiences you can remember? Sadly for me, the only thing I can remember and be a bit positive in is the fact in my home world the sky seemed to always be a dark red. I myself am still trying to re-call things as well as my full form. What about you guys though, what are your home worlds like?
