No wonder kids are afraid of the dentist

I have very vague memories of my own experiences being drugged at the dentist. I remember the strange experience of coming to and still feeling as though I were dreaming and trying to communicate with my limbs through a fog thicker than cotton candy. All I remember of my surroundings are legs and arms supporting me and a voice at my ear, and a distant awe at a doorway flooded with light.
Looking at that description, it almost seems as if I had visited the tunnel of light.
