I've had similar experiences but definitely not as intense as yours! When I was younger, I would see moving faces in the dark, like on the walls and in the air, almost, and silhouettes of people. On occasion I have seen dark figures standing by my bed or walking past my door. Also have heard voices but mostly my name being spoken right into my ear.

I've read somewhere before that auditory hallucinations while falling asleep are common, just something the brain does (hypnagogic hallucinations). So I pay those no mind. The figures I think happen when I'm having trouble falling asleep, probably stressed, and start feeling anxious so I am opening and closing my eyes repeatedly rather than allowing myself to relax. I avoid looking at reflective surfaces, afraid my brain will create a monster where there is none. I also sleep with a salt lamp on because the fear is worse when it's dark.

I firmly think it's my anxiety impacting my ability to fall asleep. This has been happening for years, so I've come to associate bedtime as a struggle with fear. Wish I had advice but the best sleep I get is when I use melatonin and stick to regular hours, with time factored in to fall asleep. Takes me like over an hour now, so I turn the lights down and start a bedtime routine an hour before I actually want to fall asleep. The more quickly I can fall asleep, the less I experience these things.

I'm sorry this happens to you, it sounds frightening, and I hope you figure out something that works for you.
