Last night I had a dream that one of my best friends younger brother was a very talented and successful singer.

I was walking with the same friend down a path in a forest. Also present was another friend of mine called Emma. Funnily enough both of these people are friends I have got back in touch with after years apart.

When I left the track I was chased by a bear.

Later on the dream I was on a bus with Emma and Leif (my first love). He was wearing blue jeans.

I understand that the path I walked with my friend was perhaps friendship as the threat came when we left it (the bear).

As to the rest of it I'm not sure...

When I read the title of your thread, I immediately thought of the expression: "Does a bear shit in the woods?" I'm not sure if it is used outside America, but in America it's used as a reply to a question where the answer is obviously "yes". So if you are familiar with that expression, it could be a way of saying that the answer to a question you have is obvious--right in front of your face.

A bear doesn't necessarily represent a threat. It can also represent healing and regeneration (hibernation).
