I have only had one or two past life dreams. My recent one I was a woman in the colonial times prob. around the civil war. I was crying because I was pregnant and my extended fam. was laughing about me–and didn’t know the depth of what I was experiencing…was a very strange dream. I mean I was in a cotton like dress/and there was a man who broke my heart…and some sort of fam. feud.
The other times I have dreamed of futuristic cities with flying cars more like planes, aliens, saving other planets from mass extinction and war. I have astral projected and went to the moon, where I saw the american flag which looked flat/more like a plaque/and was grounded to the moon by a metal cord/and pole but i thought it was strange it was lying flat, I would have hoped to see it standing up straight. I have met people in the astral plane too. I have seen lost souls calling to me, and have premonitions about future disasters and events.
I don’t think it relates to schizophrenia more-so high intuition and imagination. You can practice lucid dreaming and dream recall. Its not some guarded secret. All people are intuitive, some are just more open minded than others.
