Although I've already interpreted this dream, its always interesting to hear outside analysis:

I'm at a wedding in a chapel that has windows on the side. My view perspective is actually looking down at myself in the crowd. The me in the crowd is facing the nuptuals but I don't recall ever seeing the bride and groom although I assum they were there getting married.

Everybody is wearing green, be it dress or suit. I'm wearing red. When I the viewer relize this, the me in the crowd starts looking around and feeling frustrated that nobody informed me of the color theme.

As that is happening, I the viewer look through the windows of the chapel and see a blissfull summer day outside with green grass and trees swaying in the warm summer wind.

All of a sudden I find myself standing on one side of a river. The grounds grassy green. Theres some stepping stones to get across and I have friends that are asking me to come over. The water is rushing by quickly and it should be noted that the name of the river is the Red Cedar (red, green.)

Then as I rushed across, I fell in and felt cold as the water rushed by, the rivers known for having ecoli and I imagined little green ecoli rushing by me. I had made it far enough to grasp onto the other grassy shore of the river, nobody made an effort to pull me out but I think I got out.

Thats where it ended I think.
