DID YOU EVER HAVE A BRAIN FART?

I was going through one of my games and I was going to add a sound effect for opening a chest. And low and behold I have imported sound effects in my game. And I'm like where the ^%&% did these come from. I searched all my resource folders, which I keep neatly organized and could not find them. I searched the file name and could only find these sound files in the game and not in my resources. I tried searching the internet to see where I may have gotten them. I read my in game credits. Nothing seems to explain where these came from.

So the only other explanation is that I found these somewhere and put them in this SE folder (because they fit the game pretty well.) But I don't remember doing this and have no clue where they came from.



So did you ever have a brain fart?
