Hey /x/ long time lurker here. Hardly post

Quick back story.
Ive always been interested in the paranormal.
Had plenty of sleep paralysis experiences as well.

So, recently, ive had 3 weird experiences.
1. Few weeks ago, i had an audio hallucination. Hardly have these. I could hear a lady saying random numbers.
I cant remember what she was saying, but it made me think of those number towers

2. Again, went to sleep around 8 am that night. Woke up in a weird state where i was lost and confused.
I kept hearing a high pitch sound that would pierce through my ears. It was a very bad feeling, and it kept happening each time i was dozing back to sleep.

3. Again, earlier today, i took a nap around 4pm. Woke up around 6pm to the same high pitched sound. Happening again each time i started dozing off.

Never experienced anything like this. Plenty of lucid dreams and sleep paralysis, but never like this.

Anyone have any explanation to this?
