was getting "wonky" first thing I would check was power and ground.
When doing my Ham radio hobby a good solid electrical ground always made my antennas work better. Hummmm
I might try the "home made" grounding device he mentioned. I would use a long strip of copper mesh under the fitted sheets and connect it to a wire leading outside. Hook it up to to a copper ground rod pounded into the earth. Just like my Radio!!
My only concern would be if asleep and a electrical storm popped up, then what? Lighting strikes travel thru the ground too. Hummmm

Either grounding screw or 3rd rail.

And check the clamp on your outside ground rod connection. Decades ago some of those were steel and rusted out. Bronze or brass are the more durable materials.

I live in a town house so the condo commandos would prolly question what I was doing. The house is build on a concrete pad/slab so I could drill a hole in the closet, down into the earth and then use a new copper ground rod.
I think that would help with the lighting strike threat. Then run a copper wire to the bed...
A thought.. or just mental masturbation...😱
