Since always, every once in a while, i go like "Hey, i've seen this before"
Its about the most random things, like a scene that i often see in my dreams and forget(i hardly remember my dreams ever).. Then when its happening in real time, i remember seeing it all.
Like i saw my last day of 10th grade when i was in 8th grade. The exact amount of sunlight in the classroom, the kids...many of whom had not even joined our school when i was in 8th so i didn't know who they were..... everything was exactly as it had been in my dream.
This was only one of the more significant things that i had seen... Mostly, i see a normal conversation with a sibling or a friend, or a new place that i discover later(like a shop... nothing significant) or things like that. Its almost a laugh for people around me when i say, "Hey, i've seen that before!"
I wish it was for useful things.
