I dreamt that we had a huge garden, like the kind you would expect to be behind a huge stately home. Down the centre of the garden was a lawn, and the lawn was surrounded by water. The edge of the water was lined with concrete slabs, and there were "walls" dividing up the ponds that came up to the same height as the concrete slabs at the water's edge.

I came home one day and went out into my garden and looked around. All of the plants that were at the edge of the ponds or growing out of them were doing really well, and were a deep, lush shade of green, but the water itself was so full of algae that you couldn't see through it any more and it almost looked like a lawn.

I walked up to the water's edge, and then stepped out onto one of the "walls" of slabs that were dividing the water. I walked along it and it branched several times, and a few minutes later I was in the middle of the pond on a platform one paving slab thick.

Yu Lee came home and joined me, also working her way towards me over the slabs.

When she got close to me we talked for a while. I was saying how lovely the plants looked, but that we had to do something about the algae in the water. As I was talking I was wandering around, and several times I nearly stepped off of the platform I was on, forgetting that the green all around me wasn't grass but was water.

After a while we decided to head back towards the house, and started working our way back along the platforms. After a few minutes we realised that there was no obvious way back, and that all of the platforms ended in the middle of the pond.

We stood on one of the platforms for a while, trying to work out how to get back, when all of a sudden a moving slab of concrete came into view. It had 4 bolt holes on the top where it was obviously screwed into something under the water's surface, and whatever it was screwed into seemed to be running along a track underneath the water's surface, and went back an forth from the middle of the pond to the edge closest to the garden.

When the platform came near to us, Yu Lee and I both stepped on it, and as we did so it began to slowly sink. In a second it was below the surface and we were in water up to our ankles.

We quickly stepped back off of the platform and decided that next time it came close to us, one of us would step on it and see if it would hold our weight.

This is the last thing I remember.
