A short YouTube clip (by Anne Truong MD) explaining that erections commonly occur during REM sleep. The speaker states this is normal and can be healthy; REM is when dreaming and deep sleep stages occur, and parasympathetic activation during REM increases blood flow (including to the penis), producing nocturnal erections. The speaker notes these erections are not necessarily caused by sexual dreams and may explain but are distinct from "morning wood."
