Theres a lot of cross referencing that can be done with much of this phenomenon. As another example to what you just mentioned, people often report that UFOs will travel at a great speed, only to defy physics and cut a 90 degree turn without slowing down. This is also (fairly commonly) reported in cryptid sightings when these "animals" are moving rapidly. Taking one example, a man (a seemingly very credible one who I saw on video), saw a "wolfman-like" creature running alongside the road in the same direction that his car was going and he stated it had to be moving at least 70mph, then it cut a perfect right angle right in front of him and crossed the road at the same speed. Its an unlikely thing to make up because its ridiculous. But it does match other similar reports and many UFO accounts. Many people feel this tangible fear and dread that they cannot explain when they come across scary cryptids, and they state that the fear and feeling of evil is something on a level that they did not know existed, this is also mirrored in reports of demonic infestation/encounter. Sort of like NDE'rs describing a level of love that they did not know existed, so too does this tangible fear and evil manifest itself when these cryptids are encountered on a level which the experiencer did not know existed. Which is interesting, because nobody ever sees a bear or Tiger and goes "that creature is evil and it plants a sense of evil in my mind." People are less likely to report this sense of evil with Aliens, though the aliens do come off as cold hearted in many of the reports. But every now and then, somebody reports feeling immense love from the aliens, and when they describe this love, they sound like people describing an NDE. Aliens also communicate through telepathy, so do spirits in the NDE realm, and people often report that these cryptids can sometimes communicate through telepathy also. Ive actually started keeping track of cross similarities between these type of phenomenon that I come across. So what the hell is going on? Truth is indeed stranger than fiction in our reality. The things in the stories we invent are not as weird as the everyday experiences of people on this planet.
