My sleep had been very poor for a few years related to work-related stress. It was difficult to fall asleep, stay asleep, and go back to sleep after I'd awaken during the night. I realized that I had stopped dreaming because I didn't sleep long enough. That made me look for something beyond a pill or potion. I was slightly anxious about feeling claustrophobic the first time, but found it cozy, comfortable, and deeply relaxing. I slept that night and had a dream!
