I experienced this more than a few times. I saw a digital clock in my dream, woke myself up to check real time and the real clock was showing the same time as the dream clock. I remember searching this on google years ago and reading two or three stories describing the same thing. (Google is not helping this time though) Also years ago, a friend of mine told me about this phenomenon out of blue and asked for my thoughts on it.

Have you ever experienced this?

Do you remember reading about it? Could you provide me the links?
