I had this dream where I was in a train station and some chick snuck up behind me and stuck me with a hypodermic needle three times (once in the side, once in the neck, once in the other side) and I started to go numb. She was trying to kill me, but I was too intrigued by the fact I could touch my lip and it actually felt numb-tingly, like when you get a shot of novacaine. I woke up, and of course my lip was fine, but I just thought the fact that such an odd tactile sensation as numbness can be present even in a dream. 
Oh yeah, and earlier in the dream I was walking around all toked up. That was purty phunny too.
One more thing, hypodermic needles f—in’ hurt.
