I think you're already making a mistake in thinking about it as 'entities' and 'paranormal'. Liber O vel Manus et Sagittae sub figura VI has a great bit about this:
> 2. In this book it is spoken of the Sephiroth and the Paths; of Spirits and Conjurations; of Gods, Spheres, Planes, and many other things which may or may not exist. It is immaterial whether these exist or not. By doing certain things certain results will follow; students are most earnestly warned against attributing objective reality or philosophic validity to any of them.
Which combined with the Mathers/Crowley Goetia gives more insight into a different perspective:
> The spirits of the Goetia are portions of the human brain.
Would you question the intentions of parts of your own brain? :) Maybe! But this gives a pretty different perspective on them than external 'entities' influencing you. In the end, all that matters is that note from Liber O -- by doing certain things, certain results will occur. Whether it is external entities or parts of your own brain is kinda irrelevant to causing results.
