Interesting Subject during class time

I have always been interested in psychology. Deja Vouz is a subject that completely baffles me and I would love to learn more about it and possibly find out an answer whether it is real or not. Another issue that is great to learn about is drug use and the effects certain drugs have on the body and the brain- both longterm and shorterm effects, I have already learned about drug use in a previous pyschology course but it wouldnt hurt to learn some more!
