I'd say it was a flash back. Enough triggers were present in order for you to reexperience it. When I was 8, I was blinded by having whitewash doused in my eyes. For weeks I had bandaids on my face and couldn't see. 35 years later and a few months back, I had an eye infection in both eyes and the doctor put drops in so I couldn't see and my boyfriend had to walk me home. I suddenly started to feel like I was eight again and when he fogot to tell me to step down from the walk way and I stumbled, I started to cry like a frightened child. All the flashbacks and triggers led me back to when I was blind. Kinda quirky but harmless I guess.
