Well i tried to invoke once again since in that method i can definitely feel something weird happening. So my astral senses are still not that developed, i started by playing the enn chanting on my phone while gazing at sitris sigil then it flashed, put it under a pillow while i lie down and listen to the chanting. Visualized sitris giant sigil floating above me horizontally while emitting light which i liked to think as sitris energy pouring through me. a good hour or so i twitched alot and saw lights on my closed eye. Closed the ritual and enn chanting. lie down on my pillow (still has sitris sigil underneath) and fell asleep after that. i woke up dizzy and tired and i recall random dreams. is it how it goes for everyone?
Are you trying invoke or evoke? Those two are different 
and depends on what you were looking to achieve honestly
Invoke. Calling upon the spirits within me. My goal is to speak to them and to gain their wisdom
