On old TVs and some TV channels, I get an effect from the sound that makes me feel like there is something behind me, or something with its eyes on me. Another good example of this is the [original Lavender Town theme](https://www.youtube.com/watch?v=-sOadAaGiq4) which just gives me the creeps and has the same something-is-watching-me effect. Is this normal and is there a scientific explanation?
In: Technology
There are some electronics that emit infrasound (sound waves beyond human hearing) at a frequency that apparently causes people to have the sensation of being watched. Maybe a TV you’ve used in past did this. If you watched static etc. on that screen, you could have picked up the association from there.
