I never did a google search with the string search "cataplexy feigning death" until the other night. Interesting. Apparently catplexy is well accepted as a condition that feigns death, but noteably in zoology. Below are some of the links that google search provided. The link to the pineal gland is just something extra, but does relate to this thread and a few links about the tuatara and its pineal eye.
The definitions of feigning death in zoology are coined the term cataplexy. This behavior notes an instinctive response to go into a catatonic state in the elevations of fear and surprise.
Certainly sounds awfully familiar to the cataplexy defined in narcolepsy as well as catalepsy.
So, yes...the brain is in a state of defense as I suspect the brain to be in during sleep paralysis. Sleep paralysis always seems to take place during these states, though may not always be influenced by these states, but the communication pathways in the brain...that specific criteria...that spurs on sleep paralysis in these states may be the same without being in these states..."states" refering to cataplexy and catalepsy.
ESP activity I've suspected to be sort of a 'by product' of these crossed communication lines, as described in other posts in this thread as impulses being diverted perhaps to the thalami, when they should be restricted from the thalami, allowing sensory processing of these impulses.
The pineal gland's relation to these visions and perhaps eyesight in whole is significant enough to say "hmmm"...considering other biological notations of visual mechanisms of pineals in other animals, especially the visible third eye noted on reptiles. Granted, they are only suspicions, but they are based on factors that should raise this kind of curiosity, IMO.

Start at page 68. You might have to go up a couple pages. The link takes me to page 70.

Specifically last paragraph where cataplexy again is used to define feigning death.

Again...cataplexy used to define feigning death.

An interesting write up on the pineal gland and its suspected link to optics.

Tuatara...Note: Anyone with access to the above article, I would really appreciate a copy...thanks.
The tuatara is strongly focused, because it has one of the most primative forms of the pineal eye. This reptile has seen the dinosaurs come and go and they still continue to cling on to existance, though highly endangered, on a few New Zealand islands.
