Is he for REAL???

hi ppl... theres this guy in my art class that i sit next to and my friends keep telling me that he "soo fancies me!" my friend said that he acts really weird around me and he wouldn't approach other girls like that, and that he was so flirting with me. he just kept annoying and he disagreed with everything that i said in a jokey way ... he even bblew my face with a hairdryer!!! i know this all sounds slightly insane but is he for REAL???
