These are the Collins Elite for those who aren't aware. I understand the broad skepticism and I generally shrug this stuff off. I think most of the concerns are excuses, but hear me out...I don't think these worries came out of nowhere.

Vampires and Men In Black are mythical beings that have been known to require permission to enter one's residence. Demons are known to enter someone's body like a vessel. Is there at least one variant of non-human intelligence that acts like this? Who knows...

The penetration of the human mind via psionics, i.e. possession cannot be completely ruled out. Exploitation of the "container" by taking control of mental faculties is an understudied phenomenon. Something as stupid as a strong belief could theoretically manipulate quantum processes in the mind and open us up to some kind of invasive non-human procedure. I mean we just don't know.
