What does this dream mean?

I dreamt that there were 2 politcal leaders (butni think it was based in a differwnt centuary as the way they dressed and the way things looked, nothing was modern), one being Margaret Thatcher and the other person was not known. They were in a building (maybe a church or something). Thatcher and the unknown man were dressed in white. I believe the man was the priminisster and he wad asked a question (vant remember this) but he said something about hik doing it (cant recall what it was about), Thatcher (who was standing right next to him) said in a dominent tone that she will make sure he does it. The two individuals walked out later as they approached people who wore black clothing. They both took out hand bells, there were quite a a lot of hand bells attached to a single rope. The ringing alerted many other indivudals in white where they started to walk behind them. Then i coild see that on one side there was like a heard of people in black clothing and on their side, a herd of people in white clothing, just walking past each other - no sign of violence.

What dies this mean? I do bot think i was the leader, in fact i was not in this dream but was watching it like a movie. There were only white people in this dream, regardless of the colour of their clothes. If it matters, Margarets upcoming was before I was born (and this dream is based in a different century), never met her but read that she was the best leader of her time.
