I've had a number of cases of sleep paralysis, enough of them to point out individual ones. It started out in high school as being feeling like I
was awake and being able to see things around me. Never had a "falling" feeling, just the paralysis. I would have to will myself to wake up/move
or whatever to get out of that state. Then in college I started hearing music playing while in this state - this happened only twice, each time I
heard a flute playing, lol. A few times since then I have heard entire orchestral scores of music I've never heard before. Never chalked it up to
anything paranormal, I just assumed the mind is capable of amazing things. In fact, it kind of pisses me off that I can "hear" this stuff while
asleep but not be proficient enough to write music and make some money off of it,

. Anyway, I don't get the music so much anymore. Now I'll
occasionally get the loud buzzing, feeling like my entire body is shaking violently, and definitely the feeling of impending doom.
I'm open to paranormal things that may be possible in this state, but for me, they're not paranormal. To me I have an occasional problem with sleep
paralysis. When I was younger it didn't mean much. In college I was doing pretty well for myself and the paralysis was actually a positive
experience. The past few years I've experienced nothing but stress and my sleep has definitely reflected that with the feelings of danger.
Perception and your current state of mind can make all the difference.
Sorry for being long winded.
