Ask the Sleep Doctor | 28 |

We talked about the impact of grief and complicated grief on sleep, the most common sleep disorder(s) I see in my practice (insomnia complaints), teenage sleep-is 10 hrs too much (no, it depends), lifelong delayed sleep onset which is actually delayed sleep phase disorder, an article on Hypnic jerks at sleep onset, and ended with what triggers hypnagogic imagery. I added the reference to the Hori et al paper on topographical EEG mapping of the 9 (not 13) various stages of sleep onset.
