“The modern scientific paradigm has its strong points too, but they are far too limited to be able to explain the nature of the universe in any subjectively tangible way.

Demons and spirits exist in different planes where sometimes they enter into our world, and when they enter into our world, they can take many shapes. For instance it could very well take the shape of a severe headache or maybe some negative thought patterns occurring and reoccurring. They have many ways of entering your subjective experience, they can even take the physical form, but that is much more rare.” – The Dao
