It is the beings that give you astral projection that keep you from breathing.
They do it to keep you in a half asleep mode
Astral projection is just some kind of dreamy/hallucinatory experience given by species made of dark matter. They also give hallucinations and dreams.
You can read more about it in my book "Dark Matter Orbs Are The Origin of Dreams", search it on amazon
Or my website Dark Matter Species
Orbs are actually very intelligent life forms.
They give dreams and hallucinations to people.
Because dreams are given by another species made of dark matter.
Dreams come from an external source, not your brain, so they can give the same to 2 people if they want to mindfuck you.
