Speaking in tongues. What do you think?

Two weeks ago, I found myself inside Christ embassy (the school fellowship one.not sure what it's called) and felt as though I was possessed. I just couldnt stand the rhapsody of unfamiliar words and languages. Everyone had smthg to say except me, and it makes me wonder if this stuff is 4 real.

Am I just unfortunate that i haven't the gift or is there something we should know about the Holy Spirit and utterances?
