Been noticing this too. There's been a cluster of reports coming out of Arkansas and Missouri over the last few months that's hard to ignore. The red eyes thing keeps coming up again and again across completely separate accounts from people who don't seem to know each other.
What gets me is the sound descriptions. Some people are calling it a howl but others say its more like a low rumbling that you feel in your chest before you actually hear it. That detail crops up in interdimensional entity encounters as well - the infrasound type sensation. Makes me wonder if the Howler is something that slips through rather than a purely physical animal.
Anyone got links to the recent sightings reports? I've seen a couple on social media but proper documented ones would be better. Also curious if anyone's noticed whether the locations match up with known magnetic anomaly zones in that region cos that would be interesting.
