So for those of you that said you were interested in participating in my experiment to induce positive/negative-themed dreams - here it is!
You'll need one small thing to do this experiment: Just something you can squeeze repeatedly. If you have a small soft ball, maybe like a tennis ball or a stress ball (that's what I use), that's perfect - if not, you might have to get creative. As long as you have something you can hold in one hand and squeeze multiple times, you should be okay to do this.
Step 1: Find out which condition you're in. In the interest of keeping it mostly random, follow this link: https://wheeldecide.com/index.php?c1=Left+hand&c2=Right+hand+&c3=Left+hand&c4=Right+hand&c5=Left+hand&c6=Right+hand&t=Which+condition+will+you+be+in%3F+&time=5 and give the wheel a spin. You'll end up with either "left hand" or "right hand".
Step 2: Once you know which condition you're in, wake up during a WBTB as though you were planning to induce a lucid dream. But then I want you to take your small squeezy object, and squeeze it repeatedly in whichever hand you got for your condition. So if you're in the "left hand" condition, you'd squeeze it in your left hand.
You want to squeeze approximately once a second, for 45 seconds, then rest for a minute or so and then repeat two more times. The timings aren't vital, so don't worry about being exact with them, it's just a guideline. Also if your hand gets tired, feel free to stop there - I don't want to cause anybody hand cramps!
Step 3: Go to sleep immediately after performing this. When you wake up, try and remember the dream you had following the WBTB, or the closest one to it, and report back with the condition you were in and the theme of your dream (whether it was positive, neutral or negative in terms of emotional content). Also, please report any other unusual effects in your dream content, as it's possible this method could affect your dreams in other ways too. Please report whether you're right-handed or left-handed too, as this COULD affect results!
That's it! Hopefully we'll be able to find a connection. I'll make another post, maybe in a couple of weeks or so, explaining the science behind this - regardless of whether we find a significant result or not!
