insomnia
"I have been on trazodone for years. In the past I have tried all of the other sleep drugs but they weren't working well anymore  so I was prescribed belsomra. WOW the nightmares are awful.  You are awake but stuck in a purgatory with the shadow figures over me. I was trying to call to my wife to wake me but kept falling back into this elaborate intertwined nightmare it lasted for hours."
