Yo tommy, THANK YOU. This exact same thing happens to me, EXACT SAME THING. I always think that i've dreamed of it before, but I'm never sure If it actually did. I get this like everyday. It happens sooooooo much, I hate it. Thank you so much, I seriously thought I was the only one. It's funny though, it only started when I hit my head skiing. I remember I hit my head, blacked out for like 2 seconds, but then I was fine. But then for the rest of the day I thought I had dreamed everything before, now ever since it happens to me a lot.
