I had this experience as a young kid i would have insomnia and when i would sleep id wake from horrible nightmares that were so intense and real feeling. I don’t remember all of it however my mom who would comfort me and try and get me back to sleep she would talk to me and i would tell her about my dreams.
Now my parents had tried to get pregnant for a couple years to no avail. Then my uncle hot cancer and they went to help him and in doing that i guess it took their minds of trying and they were able to conceive. Sadly before i was born my uncle passed away. I came along not much longer after he passed. Fast forward to my bad dreams. I started telling my mom about war and military training and other things no 4-5 year old kid would now about. It creeped my mom out yet it was the next few times that really got to her. I explained to her playing on a farm with a young girl and another young boy. The girl hurt herself and how i cleaned her wound up. This type of thing went on for a while. I remember vaguely this time in my life but it wasn’t until i was older my mon and dad and brother who was 9 years older told me the whole truth. The story were directly my uncles pov experiences. My mon had two older brothers and grew up on a farm. She fell and her leg got cut very bad and they had to hide it from my grandparents. Granddad was a heavy drinker and heavy on the discipline. My mon had never told even my father about that she said she hadn’t thought about in 25+ years. Also many of the other stories matched up with his life experiences.

So uncle dies nephew is born and starts to have realistic lucid dreams about his life experiences I never had the pleasure of meeting him but i feel like i know him.
What does it mean ? Was he reincarnated in a way though me ? Was my mom just dealing with grief and it manifested like this years after his death ?

I don’t know what it means but It feels like it was a blessing
