I've spent a lot of time researching religions around the world. The only major ones I don't know much about are Jainism and Sikhism. Of the ones I do know, there's a recurring mention of things that seem either psychedelic or oddly misplaced.
For example, in the Bhagavad Gita of Hindu scripture, there is regular description of higher beings having true forms that look like a person but repeated infinitely in a long line. Such a description is also our best approximation of how our "shadows" would look from a dimension above ours.
Similarly, this description of Allah would be what a higher being attempting to look like us but passing only partially into our dimension would appear as. It would be like a cube passing through a 2D plane perfectly, any squares would see the cube as another square but shifting as it moved, before vanishing as it passed through. But if the cube went in at an angle, the square would see an abomination forming, a not fully formed shape, one that changes in size if it kept moving, one that is only partially visible because most of it is "outside" the 2D plane. But the cube wouldn't see itself as malformed or incomplete.
On a related note, in Christianity, there is often mention of God being able to "see into the hearts of men". Which would be a perfectly normal and expected ability if a being from a higher dimension looked at us from outside. They would see "inside" us without issue, because we're only contained within the dimensions we live in, and exposed to high dimensions.
There's also occasions like in Norse paganism, where Odin gave up one of his eyes for greater knowledge. Doesn't make much sense if taken literally, unless you then realise that he didn't give up an eye, he "ascended" one, to see from a higher dimension. He still has his eye, it's just not visible on our plane, and he sees more because of it.
