This is a fast way to command dreams, and change nightmares into something YOU control.
An extremely strong Will Power
Casting Instructions for ‘Lucid Dreaming, or Controlling the Realms of Night’
For when you want to change the path of a fantasy:
The most important thing to do in a dream is to gain consciousness. This is not as easy as it seems, but it’s possible to awaken and remain in the dream. All it means is that you gain control. I do this automatically at a lesser extent but as an automatic reflex to everything you need – I begin chanting for protection. Anyway, as soon as you’ve awakened, DO NOT open your eyes. That will obliterate the fantasy. Once you have awakened, you can do anything you want, but I suggest going to a deep meditative state beforehand and creating dream-weapons, for when you can’t escape. To create a fantasy weapon, you must be able to at least guess how each section would look or feel, and make it bit by bit. Anyway, after your weapon is created you can summon it anytime – just imagine that you’re holding it.
For when you want to alter how a dream passed (Temporal mastery):
Summon as much electricity as you can, and psychically catch the material of the dream, hence the need for a strong will. Then, imagine that you are pulling the fabric of the dream away, and see the passage of dream-time go backward to the previous part of the fantasy you found acceptable. Now you use you will and power to ground the dream there. It tires you out though, but at this stage you can use the previous technique to change your dream.
