Warm sensation on top of head

Hi I'm 23 years old and as I was sitting on my couch I got this sudden warm sensation on top of my head in the middle of my head but closer to left side that lasted about 3 minutes. It really freaked me out. What can it be? Has anyone ever felt this?

no you might want to see why it is happening

No. But I'd get it checked out by the doctor.

Has this sensation repeted?
