When we check light switches at night we’ll need to do it room by room in a sequential order. In other words, we leave a light in the next room when we’re checking the present one. This is so we can actually look and see the light switch as we’re checking it. The other option is to use a torch or phone light or some other artificial light. When checking a light switch we look at the controls to make sure it’s off and this is the only thing we look at for rest of system.
We’ll use the image of ice since the light switch is electrical. Ice remember tells us it’s cold, so if it’s cold it must be off.
With the light switches, we use the tip of an imaginary chainsaw to label this image to our body. Imagine a chainsaw suspended in mid-air carving out a divot in your shin or whichever body part you chose to label too. Then imagine a replica light switch is being drilled into that divot with two screws at each end. To finish off freeze that body part with the light switch.
Seal off the area with the armor. Should you worry that you’ve accidentally left the light switch on just unseal your armor, feel that frozen light switch screwed into that cut out the body part, then reseal it back over once you’ve relieved your anxiety.
