Hopefully, an expert will come on here to answer better than I.
I recall that the colours are the receptors in your eyeball still being active and sending signals to your brain. It often happens after bright lights.
The person to ask about it is an ophthalmologist or optometrist. I know it has a name and I know it isn't normal, but I don't recall the name of the thing or if it was serious problem.

No, everyone sees these. Its like when you close your eyes and you see colors. The dark room is a simulation of your closed eyes.

Don't worry, it's completely normal. :)

Omg that used to happen to me too!! I used to watch them till I fell asleep! It hasn't happened since I was like little tho
I thought it was just me too
