Several of my friends have reported seeing themselves rapidly age when looking in mirrors under the influence of psilocybin mushrooms.
   I've seen this myself, but not whilst tripping. My appearance in the mirror distorts, starts twitching it's head left and right and takes on a sinister guise. I've also had an experience where spirals, like wisps of smoke, were coming off my reflection's head.

Stuart Wilde in his steps to Infinite Self, says a good experiment is to light a candle, and look in the mirror - just stare at your throat or chin (can't remember which).  Anyways, he says you'll see all sorts of distortions and shadow-type things come out if you do this for a while.  Haven't tried it yet, would be interesting to give it a go by the sounds of it.

I finally wake up with my dog barking at me and I feel as if I surge of sort of energy just going through my body for like 10seconds and the feeling goes away.....Just wanted to share because it felt so real and have been looking at my mirror all day!:)

The dog barking at you is of particular interest to me.  This makes me think it may not have been just a dream, afterall.  Perhaps something was really happening with you...

I once had a weird dream where I woke up and my dog was barking madly.  I was young, about 7-8?  And I was very sick from an infection, I should really have been in the hospital at the time.  Anyway the dream was one of levitation, and I could actually *feel* the ceiling as if it were real.  And when I woke up, my dog was right outside my door throwing quite a fit.  So I also feel that perhaps this was also "real" and not just a dream.
