When I was around 6 or 7 years old, I was messing around on my tablet in my bed at around 11:30 PM. I distinctly remember laying on my stomach in front of my window at the foot of my bed and laying my face on one of my fists.
I blink, and all of a sudden, what used to be the night sky turned into a bright blue sky. I was in the exact same position as before I blinked, and the only difference was my tablet was turned off whereas it had been on only seconds before. I didn't even feel groggy or disoriented like I usually do when I wake up, it was like I had jumped in time or something. I went out into the living room where my parents were having a smoke by the door and told them about what happened, but they just laughed and said 'sure'.
I'm sure it's likely that I could've passed out or something, but I feel like I would've felt off before or afterwards if that was the case. It's still one of the most confusing things to ever happen to me.
