Fucked up dream

When i was a kid from the age of about 11 to 15 (Im 22 now), there was a patch of of wasteland near my house where there had previously been a huge house with a swimming pool etc and my friends and i would go there sometimes to get up to no good, like light fires and have stone fights and smoke cigarettes and stuff.
About 5 years ago, the land was bought and turned into a new street with houses and flats.

Last night i had a dream that I was walking past and the new houses had been demolished and the land looked empty apart from one row of houses which had been turned into a barn of some sort. I decided to climb in and look around.

As i was walking through, i looked around and realised that the whole place was full of elephants. About 40 elephants of varying age and size. I shat myself and started trying to walk to the other side of the land without making any noises or sudden movements. As i got halfway across the land, i realised there was a wire fence, about 6 feet high, so i climbed over it. Some of the younger elephants behind me came over to the fence to look at me and i tried to walk on but the elephants on my side of the fence started to approach me. They werent aggresive, just curious, but i knew if the older elephants saw me close to their calves, they could attack me so i tried to slowly walk away from the elephants towards the wall so i could climb out. The elephants started to follow me and surround me. I looked around again and saw some of the larger adult elephants coming towards me and i started to get quite nervous. Thats when i woke up.

The dream was extremely realistic and i could see reference points that i recognise in real life and i can remember the whole thing as if it really happened.

Has anyone else here had any similar dreams and i would like to hear some opinions on what you think this could mean.
