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’ve had sleep paralysis exactly once, but since I knew what it was I found it an extremely interesting experience and studied it while I could.
I can’t imagine the terror of not knowing what’s going on.
I’ve had it a few times. Most times have been pleasant. I saw my deceased grandparents and it made me feel happy. Sleep paralysis isn’t always scary. And one time I induced it while I was going into surgery. That was the worst thing I’ve ever experienced
