The first time I spun an airplane it was by accident (OK, all of them were!): my instructor let it happen so I could learn and for the first few seconds it was like "what the fuck did I just do and how do I get out of it?" Even though I "logically" knew we were in a spin, the disorientation of G-forces, the screaming from the stall warning, and rapidly rising engine RPM made my lizard brain very slow to react. Never been happier to hear "I've got the airplane" coming from the right seat :-)
OTOH, after that first time, "unusual attitude" training became fun. Amazing what a tiny bit of experience does to the brain.
