Wormhole?

[BB13]

So i’ve been having a pretty scary experience for a while. Sometimes when I close my eyes at night, It feels like I’m getting swallowed or shifting into some unknown and I see threads of dark matter and my body becomes lighter. And it’s a very scary experience every time. What might just happen if I let go? How dangerous that might be? How do I know that I don’t appear on some UFO and get a radar stuck up my butt or my semen stolen by grey bugs? Do you know about what I might be experiencing?

 

[Henu the Great]

You are protected by the Gods from things beyond your control. It might be an interesting meditation experience when you let go of fear. Fear has to be dropped for successful advancing. It has no place for us beyond a point.

 

[The Pythagorean]

Weird experiences just before sleep are called Hypnagogia. I experience some, not quite what you described, but equally odd.

They are benign if you are Dedicated, as Henu pointed out. They are results of a trance state. Do explore them, just make sure to stay grounded.
