Sorry of it is so long but please bear with me-

So on some nights I wake up without an alarm and it's usually 3.5-4 hours after I fall asleep. What usually comes to mind is to try to WILD. So I at on my back with my legs uncrossed and my hands by my side and focus on my breathing. I like to picture an oval with a ball going through it when I breathe hahaha. So I can never actually get paralyzed but I do get tingly and hear the ringing in my ears get louder and sometimes light just flashes so Brit under my eyelids and my heart rate goes up but then it all does down. I get so many itches and needs to swallow but I get so far that I choose to lay still. I end up laying for maybe 1.5-2 hours with nothing. The last thing that happens before I just quit and roll over to try to get back to sleep is I get this weird.. Sequences. I'm not sure if they are starting dreams or if these are actually hallucinations. Like it's usually in someone's house (complete strangers) or I am looking at the back of someone. It's not exactly me but more like the feeling of a camera. I can't hear much but I kind of have a feeling of fading to sleep but my eyes just suddenly snap open (I can kind of feel them closed the whole time). None of the "sequences" are scary so i don't thinks it's hypnogogia. No matter how hard I try to stay calm, I snap out of every one. What's going on?
