And there is a theory in the academic and scientific community at least, that what people report as alien abductions have a certain number of core characteristics that map quite closely, yearly similarly to these experiences. A lot of reports of alien abduction involve people being unable to move, seeing particular faces, hallucinating, extensively feeling like their body is floating, or they were transported. This is very similar to the experience of invasion of atonia into the waking state, waking up and still being paralyzed. As well as the hallucinations that are characteristic of dreaming and REM sleep.
