Reddit mentions of Sleep Paralysis: A Guide to Hypnagogic Visions and Visitors of the Night

Yeah, that definitely sounds like sleep paralysis - your brain is aware of what's in the room with you, and is adding freaky content on top of it...

Some people use sleep paralysis to their benefit. This is a really good guide if you're interested in learning more: https://www.amazon.com/Sleep-Paralysis-Hypnagogic-Visions-Visitors/dp/0984223916

Hey dude, you've just described textbook sleep paralysis symptoms, which as you say share a lot of overlap with OBE exit sensations. It might feel strange but this is a normal experience and you are not in any danger, and if you so wished this could be used as a launch pad for lucid dreams and projections. This might be worth a read...Ryan Hurd is a dream and consciousness researcher who also experiences frequent bouts of sleep paralysis himself so his perspective on it is interesting.

His book "Sleep Paralysis: A Guide to Hypnagogic Visions and Visitors of the Night" may be worth a read.

By the way, this book looks interesting - http://www.amazon.com/gp/product/0984223916 - but since I'm from Czech Republic, shipping would be crazy.

I'd love to find it in ebook form, but this is probably not right place to ask.

Sounds like sleep paralysis. I have been suffering from that for over 10 years now. However, I have learned how to use sleep paralysis to begin lucid dreaming, so now I look forward to it.

There is a book about it that helped me out very much and showed me how to deal with it. https://www.amazon.com/Sleep-Paralysis-Hypnagogic-Visions-Visitors/dp/0984223916
