I Was On The Floor Doing Some Stretching And Felt

I was on the floor doing some stretching and felt lightheaded. I started to sweat profusely. I sat on the couch and put a wet cloth to my face. I was told for about 30 minutes I was awake just staring and was not responding to their questions. I was walked to the shower and the cold water snapped me out of it. I had drank a lot of coffee that day and had not drank as much water as usual. Could this be dehydration or low bp??
