12th March 2017 update: Close, but no cigar! This had some impact on dreams and led to lucidity on some occasions but not as much as I'd hoped. I've taken a new tangent now and will report back if it works.
Interesting one this. I've done a lot of experiments over the years to see what actions done during in the day will "carry over" into my dreams. Recently I've been beginning to think that there's something about the focus of the eyes when we perform tasks that makes something more likely to appear in dreams. After preliminary experiments this past week I suspect that objects a certain distance away from the observer are more likely to feature in dreams than things that are close to the observer. If this is true then it's great, but the even better news would be that "close up" behaviours that may be more likely to carry-over into dreams and cause lucidity - such as writing, typing on a computer monitor, and examining the hands - can be "tricked" into appearing in dreams by focusing as though focusing on a distant object, but paying attention on the task (or more so the product of the task - such as the written word or text or images).
It's early days for this approach, but I've set up a Facebook group where others can join experiments:
Lucid Dreaming Experiments
Here's how to do the first experiment:
1) Focus on the corner of a room, where the ceiling meets two walls. It will probably look like this:
3) Focus on the corner so that it is in focus to your eyes (comes naturally, of course).
4) Get a photo on your mobile phone; preferably a simple black and white one like this "ghost" (it seems like the colours black and white carry-over well into dreams).
5) Hold your phone up, at arm's length, so the edge is "near" the corner. That will look a bit like this:
6) (The difficult bit) Focus your eyes on the corner, but make sure your attention is directed to the image of the ghost, so that your eyes are looking directly at the ghost image but are retaining the focus needed to see the corner clearly. (Looking at autostereograms is good practice for this.) That will look a bit blurry and something like this:
And that's it! I've been doing this for about a week. After many years of experiments with dreams I'm stunned as to how often variations of this image keep popping into my dreams. The clarity and "ghostliness" of the image seems to be becoming sharper with each night of dreams.
I do the exercise about six times during the day (starting from about 10am). Then, in the evening, I do it about six times before bed.
There are a couple of variations on the "ghost" approach, but these haven't carried-over to the dreams as well as the ghost has.
