I suffer from several disorders, like frequent
sleep paralysis, constant lucid dreaming, some mild narcolepsy (as a doctor told me; I don't pass out but I am dragged into sleep with very vivid dreams several times a day/night), and my REM incurs too soon.
Many times, though, I've experienced a trumpet sound as I fall asleep?
I don't have problems with my ears, I've been tested thoroughly when I had an infection some years ago.
