Yeah that makes a lot of sense, probably is just the sense of not being able to see much around me and got triggered somehow. But it freaked me out because i got all disoriented and somehow before I ended up reacting by hiding in the bushes or running away or something I somehow got ahold of reality and just walked home still couldn't help watching my back on the way home though. But I could see how with hypervigilence your mind can wander into stuff you haven't necessarily experienced but things that could be potential threats.
