Identifying a Tiny Bug the Keeps Crawling on My Skin?

I keep finding this bug crawling on my skin. I've found a couple of these and I've taken many showers and washed my bedding trying to get rid of them. They are so small that I can't find anything online as to what they are and I can't get a clear enough picture to really identify it. I couldn't upload a video so here's an imgur link of a video I took of it. https://imgur.com/a/AP3PETf
