I had a strange dream about an island called Avalon and I have never heard of it before in my life. It was really weird. I woke up in this underground tunnel with large wide windows. I got up and walked around outside where there was a gorgeous garden. I saw this really pretty fountains of water and large reptiles. I met some nice simple people and than had to return to my home. For some reason I really had to return back to Avalon. Do you know anything about this? Thank you for your time.

Avalon is the island where king Arthur is supposed to have gone after he died, you must have read about it somewhere or seen it in a movie and forgotten about it.
