Let us have a look at some environmental factors. Freeman had drunk two pints of ale-strength drink several hours earlier. He was not drunk and next morning suffered no hangover. He works, but was not overworked or under any stress, and his relationship with his wife, who still does not know of the experience, hence his anonymity in this article, is good. There are no marital problems. Freeman has never had psychotic experiences and does not suffer hallucinations. He is very well educated and not prone to jump to conclusions. The absence of any factors that suggest hallucinatory experiences mean that skeptics cannot easily resort to claims of drunkenness or temporary insanity, hallucinations and so on, the standard and rather tired explain-all explanations of the strange and extraordinary that in explaining everything explain nothing.
It is quite conceivable that a person awakening from a dream might find that the dream imagery persists into the early stages of consciousness, and I suggest that this explains quite a few sightings at night, but Freeman was awake and was definitely not dreaming of anything. We might, however, observe that he was jolted into full alertness, so there is a possibility that he was not fully awake, and the edge of sleep can be a strange time, so a visual phenomenon that was the product of his own mind cannot be ruled out, and Freeman agrees, which is why he has not drawn a definite conclusion on what he saw.
A skeptical escape route will often be that he was ill and therefore hallucinating. Certainly,fevers, which cause high temperatures, are known cause hallucinations, and Freeman had one while an infant, but in this recent case he was not sick in any way whatsoever and has been for a long time in good health. He is not taking any illegal drugs and has no medications that produce hallucinatory side effects.
While he admits that once or twice in the past he has sensed presences, these experiences have never included anything hallucinatory. This shows us that his mind is not given to express his experiences in terms of visual hallucinations
The light in the room was at quite a low level, but there was nothing unusual about the light conditions, no passing headlights that interplay with the shadows in the room, and at no time in the past in that room has there been any visual apparition or anything seeming to be one. This gives the lie to another skeptical escape route, that he was gullible. A gullible person would have taken the experience at face value, but Freeman has not done so. He is not gullible.
