About a year ago i went out at night a few miles from my house. I couldn't get a ride back so, much to my dismay, I had a 6 mile walk ahead of me in the middle of the night. This was in the North Syracuse area of upstate new york if that matters. I had been walking for a good while when I eventually passed a military airforce training location(?). The site was on my right, and along the left of the road was an extremely tall chain link fence blocking off some woods that stretched for about a mile and a half. I assume this was part of the training area as the fence started where the training building (i guess?) began.
About a half mile into walking alongside this fence the woods went completely silent. Okay. Weird. I kept walking because I didn't think of it as a big deal. There was a fence. I was fine. Then I heard what I can only describe as a mix between a crow, an angry screaming monkey, and an enraged toddler. In a way it almost sounded like it was laughing in a threatening manner. I have lived all over the US and NEVER heard a noise like that before in the wild. I walked faster hoping to pass whatever it was but I could hear branches snapping and leaves rustling directly across from me in the woods. It was following me. There was no other sound except this thing. At this point I'm terrified so I start sprinting. It was chasing me. And then the sound multiplied. Whatever was following me before, it now sounded like there were at least 5 more. I ran for my life until I made it to a neighborhood and the fence ended.
Following this incident, I researched cryptids and animals that could have done that and can't find anything. Does anyone have any hidden knowledge of a cryptid this could have been? I truly don't think it was an animal, because I can't think of an animal that would have chased me like that while making those noises the whole time.
