What do you mean by "beings"? What do you mean by "from beyond"? "Beings from beyond" as in fucken demons living is some sort of parallel dimension to ours sometimes interacting with us? Angels and shit? "Beings from beyond" as in space aliens in spacecrafts? "Beings from beyond" as in micro or macro organism on some remote planet, in some underground ocean maybe, or floating in space? All the above? Well, what do I know? I know that it's not out of the realm of possible, I know that I can't rule it out, so I guess that answers your question Personally I've seen none of that, with my own eyes, except weird lights behaving weird in the sky, that I've seen, but then what do I know?
