It happens when you are hyper (probably from sugar lol)
Hyper mind means to use the "hyper energy" to create an intense inner focus so that your reflexes, thinkingspeed and awareness go way up. for as long as you are hyper. (if you did it right)
Bob: I was hyper last night so I activated my hyper mind and did my homework 4x as fast.
Steve: O.O; wtf?
Bob: ^^ XD
