Lost three hours of time--and didn't think it strange.

My foster sister and I were on our way to our grandmothers after work about 11am. We turned off a main road onto a little zig-zag short-cut road. The road was fully lighted. Yet when we turned off to me it was like we 'drove off the edge of the world." It was thick black dark. I couldn't see her or any part of me. Then suddenly we were on the road in front of grandmothers--three blocks from where we turned.
 We went in and my sister went to set the clock for the morning, but the time was wrong. The clock said 2am. I went in the living room to find the correct time. Every clock in the house said 2am. I went back and told her that. She said, "huh?" and set the clock.
 I never thought of this incident again until she brought it up 30 years later. How strange that I wouldn't wonder why the time was so different. And I'm so curious and like a bull-dog with a bone when I have a question. Yet, I never thought of it again, until she brought it up.
 We lost 3 hours?? And seemed to not think that strange at the time. Were we abducted?
