minepiphany
Like an epiphany, minepiphany is short for miniature epiphany, which is a short and sudden realization of something previously known for the knowledge of such things to be impossible. The knowledge obtained during the very short period of a minepiphany can not be restored in any way except a random repeat of that same minepiphany. It is a sacred and honorable ability in some cultures.
I just had a minepiphany and it changed my life; then it disappeared.
