Sleep-related "Old Hag" (chest-sitting/crushing) Syndrome, succubus, ghostly voices, images, presences, threats, forces and assaults
Compiled by Jason J. Patterson, August 2009

The following are the most credible and scientific sites I could find, along with a few related sites with a more personal/supportive aspect.

Ever awakened to find you couldn't move, saw or sensed a presence, heard a voice, felt physical sensations like excessive weight on your body or  smothering, and been terrified? Before scrambling to find someone to do an exorcism, please consult a few of the sites below for information on less paranormal explanations for your experience, and make up your own mind. You're not alone, there are plenty of other suffers of this natural phenomena, that share their own experiences, and scientists that study it, as it is still not very well understood. Please note this isn't a claim that anyone with these symptoms definitely have this, or a diagnosis of any kind, just an alternative to paranormal causes, backed by reliable scientific and professional sources - it is intended to allow anyone interested in the subject to have as much varying information at their fingertips as possible, and ruling out normal, mundane explanations for a suspected paranormal event is the first step in a critical thinking approach to investigating and understanding phenomena.

Sleep Paralysis With David Hufford

Reading through your post.. this was one of the helpful sites you have suggested to look into

This - http://pennstatehershey.org/healthinfo/hie/1/000801.htm

It states...


Isolated sleep paralysis is more likely to happen during the first two hours of sleep. Not getting enough sleep or sleeping on the back may cause more frequent episodes.

Though this condition may be associated with narcolepsy, many people who do not have narcolepsy have isolated sleep paralysis. It is common in adults and is also seen in children.

Most people with isolated sleep paralysis do not have any mental health problems. However, these episodes seem to occur more often in people with:
- -  - - - - - - - - - - - - - - - - - -- - - - - - - - - - -  

I can only count on one hand the amount of times I felt frozen with fear and hallucinated during sleep..I must admit it was scary... but due to my life at the time I think it can be put down to lack of sleep and depression... for when I got out of depression..and got proper sleep, I never had any more occurrences  

This next part I found a little confusing...(from  the site I looked into on your blog)

Exams and Tests

If you do not have other symptoms of narcolepsy, there is usually no need to perform sleep studies.

I have never suffered from narcolepsy... I was more the opposite...I figured that the feelings of the hallucinations and feeling at times I couldn’t move ...was a sleeping disorder... I may have it wrong

However.. this was a good article... thanks
