When I was in elementary school (probably 8 or 9), we were all on the playground. Probably like 100 kids throughout all the outdoor areas of the playground, teachers, etc. basketball court, jungle gym, random field areas, etc. middle of the day at recess. Bright and sunny and not a cloud in the sky.
I was looking across the playground and all of the sudden there was one “flash” where everyone was running inside in unison, and then almost immediately, another flash where everybody was f*****g GONE, not a single other soul on the playground, and the sky was suddenly very dark and cloudy and stormy, and at the second “flash” there was an extremely loud crack of Thunder that rumbled and echoed for what seemed like minutes. It was clearly later in the day and I was so f*****g confused.
I made my way back to the classroom and it was probably 5 minutes before the final dismissal bell rang. The teacher was asking me where had I been? And I got in trouble.
I’m guessing I fell asleep or something but holy s**t man. I’ve never experienced anything like that before or since.
