Dream I had last night of a white bear about to attack, thoughts on what it might mean?

So I had a dream about a White Bear that in the past was friendly to me and others but now was pressed up against me basically pinning me down. I got the impression that it was pinning me down getting ready to attack me.

As I was looking at the bear whose face was very close to my face, I was kinda struck at how green his eyes were but still very aware that I could be attacked at any moment. The bear was not backing off after a few gentle pushes hoping it would let me up and I noticed behind the bear was a regular yellow sun on the right and a blacked out sun or eclipsed sun on the left. It seemed as though the bear was interested in something behind me but was determined to go through me to get it if necessary.

To my right and what seemed like some 50 feet away, there were people who I was subtlety trying to get their attention to help me scare the bear off but they could not hear me and were preoccupied with what I couldn't really tell. I recall that I was calling for help but felt like if I got any more aggressive or projected any fear in my voice the bear would surely attack me.

When I woke I started thinking about what it could mean and got some impression about it's meaning but would like others input before I say what I feel it might have meant
