Most likely the dog clutch was just barely engaged and then slipped out, after just a little movement.The bad news is the drum moved about a 1/8 of a revolution. Then it stopped moving. The input shaft felt like it just went into neutral.
Continue turning the input shaft and keep trying (to re-engage the clutch)I was able to put the shift lever back into "OUT" easy. I can't move it now.
