I have had this kl idea, which I dont know if it will work but am going to try anyway.
I like writing, so I decided that I would write about a place that I would like to visit in my dreams, a dream world. Like describe it and everything. I will have a clear image of what this place looks like in my mind, and then as im going to sleep read my writing through several times. Im going to write it as if Im actually there. For example As I walk down a long cobbled path I see in the distance..... ect ect. I suppose this is a similar idea to drawing a place, but I think it could work with writing about it.
