Fantastically captures the feeling of hypno/hypnagogic hallucination and sleep paralysis. I used to have a pretty crippling sleep disorder, took meds for years. If this is still happening to you, try sleeping on your side. You might have sleep apnea. (Also, diphenhydramine is a bad idea).
One thing that could make this better would be to correct the (minor) spelling errors (I make them all the time). If it weren't for those it would be fully immersive. Please don't take that as a critique of your writing style, it is fantastic. I truly enjoyed this game. It captured the feeling of that terrifying experience I (luckily) used to have, I would just go and edit a few words and it would be perfect.
Thanks for the game.
