I’ve got 1 dream check, that’s fairly reliable, when I need it. I check my back pocket for “heavy weapons”. Basically, think cartoon “hammer space”. It’s an almost unnoticeable check when awake, that doesn’t do anything. In a dream state however, an ak47, or a bazooka is to hand.

This is particularly effective against nightmares. My subconscious happily accepts that I can pull whatever cartoon doodad I need out of my back pocket. This let’s me jam nightmares. I’ve not had one since I trained myself to do this a couple of decades back.

The 1 trick to note, you need to “believe” on some level that it will work. It’s akin to accepting a film. You know they are just actors and CGI, but you accept it as real. This belief gives it power in your dreams.
