This sounds like some special case of Tampa Bay Super Bowl LV 02 07 21 vintage shirt. I’ve had it for as long as I can remember (about 25 years). I was 3-4 years old first time I remember waking up seeing a glowing orb flying out of my ear and out the window. Since then, I’ve seen everything from dragons, men staring at me, to animals and even fucking clowns in my bedroom when waking up at night. Some of them move some are static. They are there for 30 second to a minute, usually a black shade, that slowly fades away. It’s absolutely fucking terrifying, or was, now it’s just annoying and I try not to look around too much when waking up at night. What I’m saying is make sure this doesn’t continue when he grows older, if it does comfort him and assure him it’s nothing dangerous.
