I smoked?

Date: 10/1/2016

I picked up, lit, and smoked a pre rolled tobacco cigarette, amber leaf. I remember it being lit but not lighting it myself - I did not pick up a lit cigarette - and I couldn't do a proper drag(never smoked before) so I looked up and saw myself in a mirror that appeared out of nowhere, took a harder drag and I remember watching the mirror for the front of the cigarette to burn red as an indication of smoking it properly. I blew out the smoke and then I remember thinking 'oh shit my mums going to catch me' so I put it down on an ash tray. By this time the mirror was gone. This was at my house in the living room, sitting on the couch and facing the coffee table, that has no mirror. I don't even smoke and never have in my entire life :/ Why would I dream of smoking...?
