Was I drugged last night?

So I went to a rave and had a blast. A long time ago i used to do some party drugs (ecstacy, MDMA, etc.) but not anymore. At the last song they went hard on the strobe lights and I had a legit hallucination at each flash... it was so vivid it became hard to tell whether the hallucination was where I was or if i was still at the rave. Basically when the strobe turned on I would be at my house getting yelled at by my parents and when it turned off i was back at the rave. My friend actually ran over to ask if i was ok. I'm wondering if i was drugged (i did bum a cigarette off someone) or if i had a minor seizure... or maybe my body just released some crazy chemicals on me because of the atmosphere, or maybe it was a flashback from when i used to be a crackhead. I didn't feel high before this and i felt completely normal immediately after and it only lasted about 10 seconds. Can anyone help me out?
