I have this chakra exercise book that I love and one of the steps is grounding (where we create a home inside of ourselves and basically it is our comfort zone) so I was wondering if anyone else has escaped into their own personal dimension to cast a spell when they didn't have the materials? via specific details like if you needed a candle you would imagine the height/texture/color/width/volume/wax to the point that it feels real or is it just me?
Yes. I have done this with the Nidstang to an awful person who I just wanted to get out and away from me, and it worked. It would have been impractical to get an actual horse's skull and mount it on a pole and cover it with runes and shout stuff, so...it was all performed within that personal dimension.
