Great book, even if you aren't a student or interested in Psychology. Psychology is a vast field and this book just touches upon the different parts of it. It breaks down the study of Psychology into easy to understand layman's terms, in the Idiot's Guides style.
Freud was a hilarious dude. Basically, every dream or fantasy you have means you're either scared of something or you're a sex maniac. This book breaks it down for the average person, lets you know why people think the way they think, and why they act the way they act. Good reference book to have on the shelf.
