Anyone else experienced that?

i get something pretty much exactly like this when i have a fever, and only when i have a fever. are you sick by any chance?

YES!!!! These are my sick dreams!!! It's weird how common this is, mine is like static as well and it starts with a red background then a pink sphere, the sphere gets bigger then smaller then bigger and it makes me feel so so terrified I wake up in a sweat. I only have this dream when I'm sick though.

You being contacted by some aliens smh

I get this but with squares and rectangles sometimes circles

The static noise is probably you hearing your circulatory system while you're asleep. I used to have similar dreams occasionally interspersed with thumping like a giants footsteps that was actually my heartbeat. I've found playing music or having a fan going to provide an external noise source really helped out. This may or may not help but if you haven't tried it I think it would be worth a shot.

Sounds like a proprioception dream. Like your ears are weird from being sick so your sense of self, size, and place in space are thrown off resulting in this kind of dream.
