HYPNAGOGIC HALLUCINATIONS See images Not a dream Normal hallucination Ex. Seeing minecraft blocks NREM 2 Body becomes more at rest Slower brain waves/more relaxation Not very deep sleep “Oh I was asleep” if woken up NREM 3 Very DEEP sleep Brain waves extremely slow LOWEST Level of body activity Difficult to awaken, disoriented when awake You can respond to instructions but you do not remember doing it! (ex. Sleep walking) Growth hormones are released Sleep deprivation of NREM3 can lead to muscular discomfort and growth delays. The more physical you are during the day, the more time you will spend in NREM3 sleep. REM

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
