Lelsi2016/02/04 02:33 To be honest I don't know. I have had some situations of deja vu,lucid dreams and also this thing sleeping paralysis-which is real big deal scary thing.Also , sometimes we have a feeling that we know some person for a very long time even tho we have never met that person before.Scientific it's like this : an unborn child can sense mothers emotions and things she's going through and later all those situations look so familiar and it's actually only a situation/feeling or whatsoever similar to the one mother experienced during the pregnancy.But who knows if it's true?That's why some things are still mystery to us.
