Vintage day for the Wiki thread. My productivity is about to take a further hit.

Just looked this one up for my own info >

Sleep Paralysis

Sleep Paralysis - suffered from this myself a few times although not recently thankfully - Waking up (or as falling to sleep) and being paralysed for a short while.

Yep, I have had this about once a year for quite a while now. You do get used to it when you know what is happening, but as Wikipedia says:

Many people that experience sleep paralysis are struck with a deep sense of terror, because they sense a menacing presence in the room while paralyzed—hereafter referred to as the intruder. This phenomenon is believed to be the result of a hyper vigilant state created in the midbrain.[7] More specifically, the emergency response activates in the brain when individuals wake up paralyzed and feel vulnerable to attack.[15] This helplessness can intensify the effects of the threat response well above the level typical to normal dreams; this could explain why hallucinations during sleep paralysis are so vivid.

Really not nice the first time it happens!

If you get a proper bout, it's st scary. You are well aware if what's going on, but you can't do anything. You think your making a sound, but your not. It's a very strange thing to experience.
