if the idea of what you state in your post is energetised with a real powerful source, this would create such a powerful thoughtform that what you have written would be true. by real powerful source for this case i equate to like planetray level energy.
COming to what you want to come to, its a quite intersting thing you mention. but know that every action is the result of a type of thoughtform in this world. i would not have typed this post had not been a thought been born in the mind of mine and due to correlationship between astral and physical, i manifest this thoughform of wanting a post, to actually make the post. ..
So the real world is in itself a consequence of sort of thoughform from lots of sources etc... Magicians can use thought and consequently thoughforms to create stuff inside their mind but outside their astral bodies to eventually manifest outside their physical bodies or interact with the environment. Its where spell making also comes into play :-)
The Necronomicon might be as you say a consequence of thoughtforms. but the deities in it are much more powerful than to be result of thoughtforms. but the way one sees them is a consequene of what a sumerian culture would imprint in your mind. A hindu will see the same deities in other forms to a summerian...
OmNamahShivaya has post a picture of Inanna
http://www.sacred-magick.org/index.php?showtopic=3545 and here you would find her in a gorgeous deity in saree.
from my point of view, even if the whole human race were to meditate for centuries to create a mother fucking huge thoughtform that would definitely manifest in the real world, still the Gods would toy with this being. :-)

Keep up your reseach. being critical is what the Gods expect of the human race than to blindly believe in written texts.
