i had this dream about a year or less ago but still think of it as it was a frighting experience i was under bit of stress at the time so that could be relevant. i dreamed i was in bed and first it was very quite too quiet then i could hear a loud weird noise i cannot describe i felt like my body was rising upwards out of the bed i was trying to shout i heard a family member going into the bathroom and i was shouting them but they couldnt hear me i felt like something was covering my mouth and stuffing things in my mouth to slience me i cant remeber the rest but it was rather frightening .

I believe you had a simple case of Sleep Paralysis. We can encounter SP when our REM (Rapid Eye Movement) sleep is disrupted, which can happen when you are under stress. During REM sleep we enter SP to prevent us from acting out our dreams with our physical bodies. You have suffered one of the three symptoms: the feeling of floating. Under normal conditions, medial and vestibular nuclei, cortical, thalamic, and cerebellar centers coordinate things such as head and eye movement, and orientation in space. Because you are in an awakened SP state your brain basically gets confused because your body can't move and you feel a sensation of floating.

This happened to me before... I was in my 2nd year of community college, I believe. I woke up in the middle of the night and I couldn't move. I freaked out because I thought I was being abducted by aliens! (I was in to UFO research at the time) Panic and the feeling of intruders is also another symptom. You can learn more at Sleep paralysis - Wikipedia, the free encyclopedia.

thanks for the reply yes i believe thats true
