Evening hunt hallucinations

I know these must be fairly common in low light hunting situations, but has anyone ever fired at one of them? or am I the only dumbass?

Contributing factors
1. ground blind
2. 20-30 yard distance
3. 30/30 no scope
4. clear food plot at edge of woods
5. seated facing south, shooting towards the east
6. Shot was well within legal shooting times

I was ground blind hunting this weekend and I heard some noise coming from my left. I slowly turned my head that way and spot a huge "rack" about 30 yards out and it looks like it is moving up and down. I looked away to sort of reset my eyes, then looked back again. This time, I seen the rack again, it looked like it was coming towards me, then did a 180. I turned away one more time, then found it again, this time the rack turned broadside, so I took the shot. Also, the entire time I was seeing a silhouette of a deer body.

ETA..Just to clarify. This is the exact food plot. I was on the right (yellow lines) and the deer was on the left (orange). Basically a shot from home plate to pitchers mound.

And the deer on the far right is about what I was looking at (except had huge rack).
