I can certainly identify with those feelings there sailormoon.
Have I lived on other worlds before? I personally feel certain I have.
Am I on a mission...dunno.
I was told by a number of sources that I am very old and have lived on at least 150+ different worlds. True or not, I find it a very interesting thought. I have always felt like I had been thrown back into a dark primative past. Started getting that feeling at about 11 or 12 and it persisted and faded later in life. I still feel I have known technologies far exceeding anything even our best sci-fi has offered...in some past life somewhere.
I had a spiritualist psychic insisted I had lived as an energy being in one of my more recent past lives. I have had lucid dreams in my youth about otherworldly places.
It would be nice if a person could positively recall all that one has seen and learned from ALL past lives.
