Did i passout or was I tripping?

I was sitting chating at night when all of the suddenly I started to lose my sights (became very blurry) then i felt as if my body started to get cold on the arms going up to my head, by then I couldnt feel my heartbeat or my breathing and my hearing was gone(I couldnt listen to music anymore). After that everything became dark and I could see a brown sheet with rectangles but then again it all became dark. Then I passed out, but I do remember dreaming something before I woke up yet I can't remember what it was, and I usually remember all my dreams. I've never passed out before so thats why I am asking this.

I know it wasnt an anxiety attack since ive had them all my life and I can tell when I am having one. I was on dxm that night but it wasnt a high dose, it was just a 10 oz. bottle.

You probably passed out. Scarey.
