This is my personal favourite at the moment. I think the reason I love this so much is because it perfectly captured what I was trying to convey.
It was about a dream I had - being in the middle of a massive open field with reedy, green grass up to waist height. It was a quite dark, but only because there was such a beautiful storm happening. Lots of rain and wind blowing the reeds and the feeling of being alone with a whole heap of anticipation of a mysterious meeting/encounter that was about to happen. A giddy feeling like something huge was about to take place.
Also a warning - it gets a little louder in the last few bars of the song.
