Now one of the tools I use to tell if I am dreaming or not is my magic watch. Every once in a while I will do a reality check IRL by checking my watch. I will press two ‘buttons’ (they’re not buttons IRL) at the top and the bottom of the face of my watch. If nothing happens (or if I’m just not wearing a watch) then I know I am not dreaming. However, if the face of my watch unlatches and opens up then I know that I am dreaming. This has never failed me. Now in The Dream Realm, I will use this magic watch as a bottomless storage device. When the face opens up I can reach in and pull out anything that I want.
