I see 11:11 a lot too and i always think its a good and powerful thing.
I've read about it on different sites but now really believe the power that you give it that counts (as with everything)
Each time i see it I feel a warm feeling and connect with a more conscious part of myself. If i'm with my girlfriend and one of us sees it we'll tell the other and then we'll smile and both feel it.
Of course its not the time itself that does it but just choosing to feel that when we see it, kind of like an agreement we have with other parts of ourselves. (and probably other entities too)
So like everything in life it has the power you give it, for me i find it is a little nudge to remind me of who I really am
In many spiritual channels 11:11 (and 11/11, even 12:12 etc) it is referred to as an energy or time gate
From Kryon - End Times Revisited
This, then, plays in to these end times that we talked about in 1989. These end times are really the beginning times. How many of you have seen 11:11 on the clock? When you see it, does the energy of it say "end times" to you? Is it a fear number? Eleven in numerological terms is illumination. So 11:11 is illumination squared, if you want to say that. Illumination. Illumination. That's not the end of anything! It's a promise!
