ASMR Video - Unless you actually know what the below video is, you will think I am really wierd.
Basically the video below has sounds which make you really relaxed. To experience it, just listen for a little bit. Don't be biased, or think of it oddly. Just listen to it like a regular song. Most people, but not everyone, will notice a tingly feeling in their head, but only if you aren't thinking of how odd the video is.
