I'm thinking this would work better if you went around your backyard touching things in the evening before you go to sleep so that you have fresh memories of the tactile sensations (as well as making it a routine that might surface during your dreams).

Now a question though: I usually wake up after only 5 hours of sleep and have to take a bathroom break before going back to bed, otherwise I can't sleep comfortably for the remainder of the night. Would this inhibit the effectiveness of the procedure do you think? (ie: can you try it out and see if there's a marked differance?)
