Yes I did this and it was an excellent experience which lightens my load in life every day!

I was lucid and I focused on my childhood bedroom and bam I was there! Not a back-in-time room but, as I understood it, a room created in a nonphysical area that I could always go to. I was vividly lucid and touched everything, I knocked on tables, and felt the carpet amazed at how really real it all was, it really was all real! I saw both my two bikes as a kid there in the room. The room was perfect perhaps more perfect than it ever was in reality. A woman's thought said to me "you can always come back here." That made me happy and it still does.
