Does this sound like I got roofied?

Ok so.. I know this usually does not happen to guys. Basically I was at my friend's college partying and we had liquor and we were like we need a chaser. I don't remember how it came to be but somehow we ended up with a 2 liter sprite in our hands it was like 11pm.. Next we left the party after finishing the captain and sprite, went back to my friend's dorm, got more alcohol, and returned. We drank and eventually some stuff went down and they kicked everyone out, it was about 12 am at this time. We were walking laughing having a good time because my friend stole their orange juice so we could use it as chaser =]. So basically the next thing I know it's 5:30 am, and it was like one of those how did I get here drunk wake ups, except I was awake. It felt as if I'd been in a hypnotic state zoned out and I returned to reality I was just staring at the floor by some building like 6 blocks from my car and I was like wtf where is everyone how did I get here. My friend who didn't drink that sprite and did not experience this was wondering why my friend and I were acting so weird he said I was not talking and I was walking 30 feet ahead of everyone with my head down. But yeah what kind of drug erases all memory and puts you into a hypnotic state without knocking you out? I've been drunk many many many many times and I have NEVER experienced that. It was like my soul reentering my body it was so trippy!
