I had a very weird dream not to long ago and it's very confusing.. well it me and another girl flirting, joking around, holding hands, and kissing. But the strangest part was it wasn't my wife it was some other girl that I have never met before.. So my main Question is am I hiding something that I don't know or am I having other thoughts about other women?

No, it's actually quite common to have these dreams. Don't overanalyze it, it's really nothing.

OK thank you very much

When we dream we connect to our unconscious mind. Our unconscious mind can make connections between seemingly unconnected things. In this case what I'm interpreting as strong emotional feelings and a stranger. It is quite normal and certainly doesn't mean you want to cheat on your wife.
