20th May 2011- I had a lucid dream about the world supposedly ending on may 21st.

I was in my house with my partner and kids,it was may 21st so we were looking out of the windows,watching the news for anything happening regarding the end of the world,2nd coming of Jesus or rapture. It turned 6pm and suddenly the ground started to move under our feet, it felt like the building was riding waves! Waves of movement not an earthquake.We all sat huddled in the middle of the room until it stopped and I reassured the kids that we were going to be ok. I wasn't scared. I was excited.We looked out of the window and everything had changed. The colors of things where different. Things looked mystical. There was giant cows bigger than elephants grazing in the park but also these dark man size fairies/beings watching over them. I shut the curtain quickly when I noticed one of the beings looking at me. I felt quite uneasy about them. The dream then jumps to my old house. The situation is the same but location changed in the blink of an eye. I am looking out of the window here and the stars start to fall out of the sky. My heart sinks but then they bounce back! The stars then turn into UFOs which start buzzing around the moon and also around the top of an extinct volcano in my town called arthurs seat.
I was astonished when I called my family and partner to see this and they couldn't see a thing! I mentioned the earlier cows and beings and none of them saw any of that either! I was in the middle of trying to convince them of what I was seeing when I woke up.
I got out of bed and looked out of the window to see if things had actually changed but they hadn't!
Also there was no change at anytime in my waking life on may 21st at all. I was disappointed with reality!

If anyone has any insight into this I would be grateful
