A state of mind when one is more than a little ditzy. A level of interacting that is beyond air-headedness. To put it simply, the lights are on, but no one is home. The term is somewhat a reference to the character of Dory
from the movie Finding Nemo, since she is rather spacey and forgetful at times.
Dory, in Finding Nemo, who is the perfect representation of 'doryish' since the word was named after her:
"Are... are you my conscience?"
"I shall call him Squishy, and he shall be mine, and he shall be my Squishy."
"Okay, he either said, 'move to the back of the throat,' or he 'wants a root beer float'."
