well to be honest a barely never get deja vu. but when i do get it, i get it strongly. it never just a feeling i get when it like "i've know i've done this before"..
its like this; i'm in a middle of a conversation, then all of a sudden i get that uncomfortable feeling. but straight after that feeling i get an image inside my eyes, from the exact point of view to where i was already standing. it like a vision from a past dream or something but its never afterward for some reason, its always when i'm actually doin it.
but the strangest and weirdest one would have to be when i was a kid. i was just playing around with a blown up balloon, just hitting it up in the air. then i got this strong vision (from a past dream), except in this one i was still playing around with the balloon and watching the vision like a movie or something.. i was like seeing the vision at the same time as watching it actually happen, but the vision was like 5 secs a head of what i was doin. afterwards i was in complete shock thinking "did that just actually happen?". i was a little freaked out and thought there was something wrong with me..
but i guess i'm glade that its only ever happen twice for me in my entire life.... but every now and then i get the same but really weak feeling, but i just shrug it off.
