I have been successful doing RC Reality Checks with a “Dream Watch” <-- (is a digital watch with some alarms and countdown timers)
Basically I found the RC to be key in achieving Lucid Dreams for myself in my experiments. Basically I have a Timex Ironman Triathlon watch. It’s a great watch because you can use the computer to program its alarms, timers and features. You can set 10 alarms and 5 countdown timers. Perfect for the experiments I have been running.
Anyways I set the watch to go off every half hour with the hourly chime and a 1 hour repeated countdown timer. I also set the alarms but had no success using the alarms at night. I never hear them.
So every half hour I would check the text on the face of the watch three times to ensure that the date read correctly and if the watch read correctly then I would say out loud “I’m not dreaming”.
I had been doing this for about 5 days and was frustrated with this technique, thinking I’m never going to dream about my watch, how is this going to help?
Unfortunately that is the wrong way to look at the RC with a watch. A subject that is mentioned a lot in information of Lucid Dreaming induction techniques is that it’s all about awareness. This is absolutely correct in this case. Reinforcing this technique every day does not make you dream about your watch but makes you aware in your dream that you have a watch.
On my 6th night an RC with my watch induced a Lucid Dream. In the dream when I asked myself the question "Am I dreaming?” my first instinct was to do a RC with my watch. It worked perfectly, the first time I read the watch it looked fine, the second time the text was jumbled. Not sure still, I did it again with the same result. I then thought that I was confident that I was dreaming and away I flew.
The problem I find with trying to use the watch as a “DreamSign” in your dream is that you are at the peak of your awareness just before a potential Lucid Dream. So that even if everything that is happening in your dream is really odd you don’t realize it because everything seems so real. Your body has no hard input that you’re dreaming because all the input is now coming from your brain as oppose to when your awake, the input comes from your senses and your brain. This is why the RC with a watch is so helpful it provides the input your body needs to make the decision.
