None of these fits the picture of biblical intercession. It appears that the Brownsville team just makes up things as it goes along. Hill, by his own report, functions on three hours of sleep a night. Blue hazes are not in the Bible. They weren't there at Pentecost, nor on the road to Damascus with Saul of Tarsus.
Blue hazes can result from sleep loss, and perceptual difficulties as a result.
Blue hazes speak more of altered states of consciousness or the paranormal, than biblical encounters. It is where mental images can be interpreted as external objects. It is associated with Scheerer's phenomenon, which is triggered by psychological, chemical and sensory changes. Eye fluttering, seen in emotionally charged meetings stimulate entopic phenomenon. Perhaps, entopic phenomenon has been stumbled on by and unbeknownst to the Assemblies of God.
