Fear-inducing moments.

[KarlYoshimura]

Do any of you experience spooky instances where intense concentration, or states of little to no awareness, yield a strange frequency-like sound and a subdued feeling of dread?

 

This could very well be anxiety, yet I've been grasped by these unnerving effects more than once, usually before sleep. It was experiences such as these that ended with a full audio hallucination from what could be my tulpa, yet there are too many unknowns for me to identify what is happening and if what I'm undergoing can even be described as reality, and not some bare hypnagogic state.

I don't know much about hypnagogic states, so I can't say if that's what you were experiencing or not, but it does sound like it's at least partially related to anxiety. Sometimes when I force when I'm feeling stressed or or anxious emotions I get a bit of a creeped out feeling. No strange sounds but there is a definite feeling of dread at times. Much like a mild paranoia. When this happens I normally have to stop forcing and take a few moments to myself to calm down before I can go back in active forcing comfortably.
