Longest: 2 yrs
Shortest: 20 minutes

With the 20 minute one, it was a Jungian analyst. After some initial stuff, I shared a dream that I'd had the night before that felt significant. She said maybe one sentence in reply, and it was so on target that I got scared and walked out. I wasn't ready. I tried Jungian analysis again later on and lasted a couple months but just couldn't hack it. He was very good, though.
