and could mean lots of things, like:

(Humans don't need to observe rationality all the time, sure perpetual hallucination is undesirable)

--One longs to meet deceased loved ones somewhere in time-space

--'Pagan  spirits', like one believes there is a god/goddess dwelled inside an idol.

--'Evil spirit' lke the devil inside an erected penis of that Italian Decameron tale I mentioned(And the vagina can cage the devil).

--Hindu sadhus can live without food or ancient hindus had flying saucers.

......'Spiritual' could be silly or bad, unlike what Xtian evangelists or hindus try to blanket imply as something good
