Possible! I actually had my bed at an intersection of fields of 4 runs of wires (hidden in walls ceiling amd floor) and caused myself severe chronic (debilitating) fatigue for a couple years. Happened after a smart meter installation. Meter quit, symptoms suddenly resolved. Turns out that’s a real thing, though people were just being dramatic When I used to read about them.
On further testing, I have a sensitivity to about 30’ or closer to a WiFi point, it will wake me up constantly at night. Turn it off, sleep fine. I still use WiFi, but on its lowest power setting, and more than 30’ away.
There are wires which offer much better shielding than the typical ones that are used. It is too bad the cost of ripping open walls and re-wiring is prohibitive to most people.
