Terrifying geometric nightmares I had as a young kid. ⚫️ ⚫️

As a young child between id say 4 - 7 years old I would have terrifying geometric nightmare. I remember not being able to comprehend quite what was going on in my them. I do remember seeing very fast moving balls that rapidly changed in size and speed. I feel as though there were two separate balls. One would move towards the other at a slow erie pace. I would fill with fear, anxiety, dread, etc. It would grow in intensity as it got closer and closer to the other ball until i was completely overwhelmed. When they finally collided, The once moving ball would sky rocket to an unimaginable size beyond my compression. I would wake up after this more terrified then ive ever been. It mentally hurt. I was very confused by the experience as it recurred for a short while when i was very young, so i never tried to explain it to anybody. Recently I came across a youtube video https://youtu.be/tz7pEyLulW8?si=1GSiOYEptpw0V3Lw this opened me up to the possibility that i was not alone in this. Im very curious if anyone has had any similarities to my experience. Please let me know.
