I think this might be more than hypnagogic hallucinations. I've been having these symptoms for awhile. I hear voices when I'm about asleep and keep waking up. I get really vivid dreams. When I'm relaxing I get vivid closed eye images. I did have this checked out and they mentioned stress and anxiety. That was awhile ago and I still have these symptoms. I'm trying to find a second opinion. Most places are booked for awhile.
