I woke up from a dream and was in the perfect state to do a DEILD. I hadn't moved an inch and eyes were still closed.

I was in Sleep Paralysis, but I could hear my heart beat in my head/ears and it sounded like it was beating so freaking fast. Way faster than normal. It freaked me out so much that I forced myself to get up (thus ruining my attempt at a DEILD).

When I laid my head back down on the pillow, I could hear the faint sound of my heart beating and it sounded normal again.

So I laid back down and tried for a WILD, I entered into Sleep Paralysis again and I could hear my heart beating super fast just like before.

If my heart was really beating as fast as it sounded, I felt that it would be dangerous.

Was this rapid heart beat all in my head?
Is this a common experience when in the Sleep Paralysis mode?

I sometimes hear people describe Sleep Paralysis as there being a vibration.

Maybe I was confusing some audio vibration sensation with my heart beat? Anyone have any advice or comments on this?
