Large octagon shaped ring in the playground area of an elementary school… about 10-13 feet wide I’d guess. Has turf inside. No markings inside. Sides are about 3 feet tall. I have no idea what elementary sized children would use this for????

I don't know whether this is paranormal or not, but I'm truly baffled and out of any possible explanations.
After being gone for 12 hours, working night shift, I got home at 6am. I hopped on my bed and relaxed a bit. Nothing was off. When I was ready to go to sleep, I got under the sheets and felt a cold wet spot at my foot. Jumped up, hit the lights, pulled back the comforter and polar fleece to discover the regular sheet and fitted sheet were both soaking wet in a large semi- circlular shape stretching over the edge of the bed.
My first thought was a possible leak, so I examined the ceiling and found no signs of water. That still wouldn't explain how a liquid from above could leave a blanket at the end my cat sleeps on, the comforter and a polar fleece sheet bone dry with the sheet underneath soaking wet. Nothing was wet underneath my bed or from the bottom of the mattress either. It's beyond doubtful my 20lb cat could have somehow gotten himself under all of those blankets, to the end of my bed and leave some type of liquid behind - while everything was perfectly intact. There was no smell at all. Unable to do immediate laundry, I let the sheets air dry when I was at work the following night and came back to discover a small stain.
Looking for anyone to weigh in and shed some light on what possibly could have happened here. This was 2 years ago and I drive myself crazy thinking about it.

Early morning after big waves

So.. this just popped out of my finger

Itchy white rings/semi-rings that spontaneously form

Bought a minivan recently and kept finding spiderwebs, bug bombed it and found ''these''. What are they ?

Every pair of jeans I buy, no matter the brand, gets a hole in this same area within 6 months.

Gf says it looks like an "alien thing." I think that I could use it to pick up coins after I've dropped them. Yes, we found it in that baggie. Thoughts?
