No, when I write in this forum about my experiences, they are my real-life experiences. When I write in my blogs, those are also my real-life experiences.
My imaginary experiences are written in a separate notebook - they are all really the writing-based sorts of LOA exercises. However, these days the writing-based sorts of LOA exercises are no longer my favoured methods. My favoured methods all involve closing my eyes; relaxing; going to alpha; visualising my intentions etc.
As for the "My Powers Are Vast" thing, I must admit that for the purposes of my IM sessions, increasing my LOA abilities is one of the more regularly recurring intentions. In other words, I regularly intend things that are designed to make me better at LOA / IM / magick etc.
I do believe it works .....
