UAP stories I know from 1940s:
During a famine, my family went to our shaman ancestor's grave for help. A whirlwind came out of his grave, flew to the water and scattered fish.
Later our haystack was stolen. They went to his grave again. The whirlwind flew to another village and brought back the haystack.

My other relatives encountered what they thought were spirits, Bigfoot and aliens. Some of those intelligences were seen by multiple witnesses, left footprints and had smell. At least one person died during an encounter (was 'scared to death'). And my uncle died in childhood like in supernatural abduction folklore (them fairies take only boys).

The latest encounter happened last year. My mother came to visit me and I told her about bilocation and doppelgangers. The next morning she saw me walking out of my room, looked back a moment later to greet me but I disappeared and the door to my room was closed. 

What happened? A non-human intelligence shapeshifted into me and even materialized a copy of my Crocs?

Here I posted how my mother encountered my doppelganger. It could mean that a form of non-human intelligence shapeshifted into me and materialized a copy of my Crocs. Like WOW, fellas. Do they find human bodies and Crocs comfortable?
