Conditioned psychosis.
Some people hypothesize that he may have witnessed it happening, but there's no evidence that Jesus celebrated Hanukkah. In the canon, there's reference to building a 7-branch luminar, but in the gospel, what Jesus apparently told his disciples was to rememorate his death at the Pantecost.
Considering that Christmas was borrowed later from European pagan pre-Christian origins, it has no apparent relationship to Hannukkah either. There's no evidence that Jesus celebrated that.
The "demonic control of space-time" is superstitious nonsense adapted with pseudoscience for the radicalization of a new audience. Jesus doesn't seem to have been mentally obsessed with cubes. He had no idea that space-time existed and it's not in the canon.
When he appeared to me, he raised my "etheric body" upwards and only said: "you're son of God" and left. No mention of metatron, demons, angels, cubes, winter or light festivals. Today I consider that this was just one of my interesting sleep paralysis episodes. His appearence was also like the JWs depict him, because I was raised in that cult, suggesting that it was a very subjective experience, influenced by my own memories. Then for the JWs that's controversial, because they don't believe that any divine manifestation is possible or necessary anymore, because of the scriptures "witness". Ironically, to them, this means that any manifestation would be demonic. Then only the "annointed" are "called son of God", a 144k elite supposed to have been sealed by 1914. When I told my dad about it, he asked me if I was taking drugs (I wasn't). But if it was true and important, "Jesus" should have said it, no? It'd likely be a mainstream Christian doctrine, at least. But no cube obsession in the gospels. For Catholics, this "vision" would only affirm that I could expect heaven after death, I suppose.
In any case, I'm no longer a believer. Arguments from ancient human tradition and pseudoscience don't dictate my life.
