Am I hearing the WiFi/radio waves?

I noticed that mostly in the evening I hear/feel a vibration in my eardrums. It happened in my previous and current apartment and maybe even before that. It's been years and I've never really talked about it to anyone since I assumed it was just a sort of tinnitus. The only solution I have to avoid/reduce the vibration is to lay down, change the height of my head (removing the pillow or sitting down on the floor instead of the sofa for example). So, am I hearing radio waves or do I just have weird eardrums?

Ps : I regularly experience tinnitus but this is different because it's more a vibration than a eeeeeeeee sound
