I need help in interpreting a dream I had

Can anyone help me interpret a dream I had about a week ago? I was inside a large building, maybe a church? We were preparing for a big event. I was wearing a blue gown which seemed like my 8 year old daughter's flower girl dress she wore at my wedding. I asked what I could do to help preparing of this event. I was asked to help clean mirrors on a wall that was in some kind of a mural. I took my time cleaning them and ask about cleaning behind them. A lady said not to worry about that part. People started coming in and I was feeling a little panicked. I had someone help me fill up a baby bath tub with water for myself to climb into. I was going to play a part with this baby tub. I was going to be a mermaid.
