This video I sent is one example of ASMR. The whole idea is this concept states people may get a relaxed feeling by hearing certain sounds and so on.
For example, in this particular video, it's most likely the sound of her writing on a book, or the sound of the measuring tape. The idea of measuring the nose is a little silly to be honest.
There are many others, for example, they pretend to massage you, or they pretend to cut your hair
Its an interesting philosophy. I'm not a huge fan of it myself, I do for the most part find it a little funny, but I wondered, if it worked on someone, would it be haram for a male to watch a female video, if that was to help him sleep.
