It’s called hypnopompic hallucination.
Unlike with sleep paralysis, you can move and talk while still seeing it and it will last a few seconds up to a minute which can seem like an eternity.
It usually fades as soon as you turn on the light, but for some very few people it does not and persists even after turning on the light.
Here’s an example of someone who often experiences these and has started recording themselves: https://youtu.be/bEMGZNvETMQ
Why YSK: because it’s very scary and unsettling when it happens and since you can move you don’t believe it’s sleep paralysis and can’t explain it. This might explain many of the “monster or spirit at the foot of my bed” sightings that we often hear mentioned in horror podcasts.
I absolutely need to know more about that last part.
Sorry for the late reply. I was in high school when this happened. I had to get my stomach scoped. While they were getting ready to put me to sleep they asked if I wanted to do laughing gas. I said sure. I had never tried it and it sounded fun. While they were doing this I thought to myself that I wanted to try to force myself to stay awake and see if I could do it. Or at least make a mental note of everything that happened to me and observe it. The laughing gas started to kick in and I started to laugh uncontrollably. One of the nurses hadn’t seen it used before and couldn’t help but laugh at my non stop laughing. I don’t remember an IV so I think the anastesia was administered with the laughing gas. Time started to get strange, everything slowed way down. A tingling sensation was spreading across my body. This tingle turned into sharp jabbing pains as if I was being stabbed by thousands of tiny needles. At the same time sounds around me started sounding echoing and distant. I was starting to panic so I decided I should let the doc know. That’s when I realized I couldn’t move. I could barely move my eyes. I also realized I was still laughing. I couldn’t speak either. I tried to scream but the only voice that actually screamed was the one iny head. I was terrified and everyone else in the operating room seemed to be happy. The pain from the tingling was getting worse and my ears were ringing so loud I couldn’t here anything. I felt like I was stuck in a black room with 2 windows to the outside world (my eyes). It felt like an eternity I was stuck like that. In reality it was probably less than 10 minutes cause the procedure hadn’t started yet. I tried to force myself to fall asleep but couldn’t. I started to wish I could just die cause that would be better than the hell I was in. Then blackness for a split second.
The next thing I knew I was in a different hospital room crying and super nauseous.
