One of the main psychology sections that I will remember five years from now is the lesson about the Biology of Sleep. I had never studied the sleep cycle before and I thought it was really interesting to learn that our bodies have their own biological clock and it's not necessarily my fault if I start to get drowsy in psych lecture ;) because it's my body's natural response! I also was interested in this topic because I talk to so many other people that have such a hard time falling asleep and they wake up a lot during the night but I can fall asleep within 5 minutes of laying down. It always seemed so weird to me that I would never wake up in the middle of the night and it was interesting to read that section in the book and figure out that it's not that I sleep different than those people, I just don't remember my dreams and I go into a deeper stage of sleep that some people might. I was also interested to find out that we go into REM sleep multiple times in one night and I will never forget that because sometimes I remember dreams from these different stages. Overall I just thought this was an interesting topic and I don't believe I will ever forget the Biology of Sleep.
