Hypnagogic imagery is often auditory or has an auditory component. Hypnagogic sounds vary in intensity from faint impressions to loud noises, such as crashes and bangs (exploding head syndrome). People may imagine their own name called or a doorbell ringing. Snatches of imagined speech are common. While typically nonsensical and fragmented, these speech events can occasionally strike the individual as apt comments on – or summations of – their thoughts at the time. They often contain word play, neologisms and made-up names. Hypnagogic speech may manifest as the subject’s own ‘inner voice’, or as the voices of others: familiar people or strangers. More rarely, poetry or music is heard


I hear sounds. It started as faint notes when I was about 9 or 10. I am now able to play whole songs in my head. I can't seem to start it up willfully though. Yeah sounds crazy I'm sure. It has to be extremely quite or quite noisy. Ither way I have to be VERY focused on it. Nothing else exists. It usually happens when I am focused on painting or just well focused on anything then a familiar note starts ringing in my right ear. I can choose to loose focus or begin to "play" a song in my head. usually starts with a single note that reminds me of a guitar solo then I can add vocals. yes singing and guitars in my head. I can feel my inner ear twitch as the notes play out. I have also been able to change the music. yep
