i'd like to share i dream i had a few years ago when i did AP occasionally. I didn't try AP that day. Dream was very vivid and realistic, i don't think i had a dream like this ever again.
A little bit of pre-history....i remember my mum talking about her ex husband(before she married my dad) and that she had an abortion....didn't think anything of it then, untill the dream.
So, in my dream i'm in what looks like an abandoned warehouse, it wasn't scary though, it was very light...big windows, walls painted white inside. I found a boy there, i'd say he looked about 8-10 years old...he spoke and he asked if i was Valentina(my mum's name) and i said "no, i'm ..(said my name)" and instantly he seemed very happy...and at that point in a dream i knew he must be my brother...i don't know why, i just did(i've nerver even thought about it before the dream). I also remember him saying that my grandmother and grandfather brought him here to meet me.
When i woke up, i was so emotional...happy bad sad. I even cried later that day.
the only thing confuses me is his age...in life he would be at least 10 years older than me...but i guess there is no "time" there.
Interesting dream. Your grandmother and grandfather are living with you or not. You said that he looked about 8-10 years old. How old are you?
I'm 27 now and when I had this dream I was 18 or 19. Both of my grandparents died 2-3 years before the dream.
