A potentially rational explanation (though I don’t necessarily believe in these inter dimensional beings) is that, these beings take a form familiar with to us explicitly to communicate.
The google research about communicating with animals got me thinking. Inter specious communication may be impossible without actual embodiment or holographic display. I.e if we wanted to speak to a bird. We might need a little hologram that also does a little dance while chirping.
The same be happening to us when our brains become susceptible under DMT.
