Is hypnosis scary?

Hi, I am in my last year of school in college and am presedent of a music sorority. Next week we are going to induct new members and have a lot of fun during or pledge and after pledge week. During all this our sorority has hired a hypnotist to perform and as the presedent I will have to volunteer and get hypnotized. I am really worried about this because I don't want to embar myself and am worried that hypnotists could take advantage of me. Has anyone here been hypnotized and knows what it's like? Does it hurt and does it make you all suggestable afterwords? Or..is it just a lot of fun. I want to have fun next week and participate but...this nervous I doubt I can. I appreciate any help.
