I've had that happen a few times recently . . . And you are correct, it is scary. Especially on group rides I tend to follow other riders and not look at my route sheet and occasionally (thankfully not real often) I realize I don't know where I am and I'm asking myself "What road are we on?"

It usually comes to me in a couple of seconds but those "Twilight Zone" moments always make me think "That was weird. Is this old age creeping up on me?" I'm 66 as a point of reference.

Sometimes I experience those "zen-like" moments noted by Biker395 yet thankfully his "chatter-box-ness" prevents any such instances when actually riding with him!
