Gotta' love moments like those. Rest assured, there'll be plenty more. I had two zeds spawn next to me once, so I booked it around a house attempting to break their line of sight on me around a corner .. Yeah, turned the corner and there's two guys with guns crouched next to eachother. At that point I'm like, "Really!?" Fortunately they didn't notice right away, and the hail of bullets I heard while running my ass off were intended for the zombies I believe. I wasn't hit at all.
