Recently I've been waking to weird sounds, like a shot going off, really loudly, but INSIDE my head - rather disturbing!  Has anyone any idea what this might be, please?

From time to time I, too, have loud but very brief sounds occuring, that's how it sounds like, inside my head. Very realistic, but sort of too realistic, as if the sound source would be very near my ears. When it happens, it happens only in the state between being awake and asleep. It would happen a few days in a row, and then it's over again. Don't know what it is.

Spooky

Could be you slamming back into your body as you wake up.

As far as the bed direction i personally perfered north/south direction,  i sleep better that way.

Where earth's magnetism pulls energies....not sure about that "Betson" could be true i don't know, i just know i sleep better facing North. Maybe someone could put us in the right direction here..

As for noises from time to time I, too, have loud but  brief sounds occuring inside my head. Very realistic, as if the sound source would be in my head. It happend in the state between being awake and asleep in meditation only.....
  Don't know what it is but think is my HS telling me to pay attention...lol

I would sometimes experience loud pops, or clicks, while in deep meditation.  I associate them with shifting levels of consciousness.  Sometimes they occur the moment my awareness returns from periods of unconsciousness during very deep meditation.

Hi karalok  i get this as well but also church bells clanging in my head and waking me up in the night.

Love and God bless  love juditha
