What does it mean to watch yourself sleep?

[Lollypoppet]

Hi all,

I'm sure this may be posted somewhere here but i couldn't find it :/ I've recently, since summer been having dreams about watching myself sleep just before I wake (which is scary because i wake up in the dark and im scared of the dark)...I saw someone put a caption on a picture on Instagram that when this happens its our 'spirit' returning back to our bodies, and that the real challenge is to remember what you were doing before that moment of waking up.

It does scare me a little, but why does this happen? what exactly does it mean? and does anyone else remember knowing that they do before they wake? x

I've been looking up things on the internet, but i dont find anything entirely helpful xxx
