what are the effects of ghb?

i was at a party and i barely had anything to drink. i felt sick so i went to the restroom to throw up. after that my head was slightly spinning so i sat down on the sofa, after sitting for about 10minutes i decided to lay down. i then slept for anywhere from 30minutes to a little over n hour not exactly sure. when i woke up i wasnt feeling sick or anything? does this sound like ghb? would i have woke up if someone tried to rape me? i woke up because one of my friends was poking my face..
