I can so relate to this! Was shooting yesterday at par first 6 holes. Hit a solid drive on the 7th ( par 5), and I get to my ball with 200 yards to the green, grabbed my 3 wood, and standing over the ball, my brain literally short-circuited.
I can’t explain it better than I had no idea what to do next. Freaked me out!
Put the wood back and grabbed my 4 hybrid.
Mentally went back to “posture, grip, ball position, breathe, slow the takeaway, back to target and fire the hips”.
Everything was fine after that but it was so weird.
