could post mortem brain activity be a proof of the three dimensionality of time?

Canadian doctors highlight a case where brain activity has been seen in a clinically dead person 10 minutes later. See here:

Could this be a proof of the three dimensional nature of time? The Davies Hypothesis
posits that the brain operates in three dimensions of time. 'Unreal' time, associated with the past, is responsible for knowledge and memory. 'Real' time brain activity continuously monitors the senses in the present, allowing us to identify our situation in the here and now and giving us understanding. 'Imaginary' time, associated with the future, utilises knowledge and understanding to find solutions and suggest courses of action. It is also responsible for dreaming, the acquisition of wisdom and appreciation of the arts and the abstract. The brain operates with all three aspects of time, often at the same time, leading to rapid response. But where's the proof?
It is my belief that when the heart stops. so too does 'real' and 'unreal' time leaving 'imaginary' time to function alone until lack of oxygenated blood causes the onset of decay. During this period, the 'imaginary' time function continues to dream, preparing the body, as it has since embryonic days, for what comes next in life, in this case final death. These final dreams as with many may come with visions, often of peaceful scenes of gardens, tunnels with comforting bright lights exuding feelings of sublime ecstacy. Often these visions have religious themes, but nearly all, I suggest, lead the dying towards a peaceful and often welcome end.
Are there other conditions that point to the brain operating in three dimensions of time? What about a condition from which I suffer- sleep paralysis? The condition arises, usually in bed, when a person sleeping soundly becomes aware that they cannot move their arms and legs although the muscles of the heart and lungs continue to operate. This terrifying condition causes panic which can last for what seems like minutes. I try, with great difficulty, to attract my wife's attention and she, recognising the problem, has to shake me, often very vigorously, to full consciousness. Medical web sites suggest the condition is not serious but I believe that those who die of heart attacks during these episodes cannot tell their stories. It really is frightening but what causes it? In this case I believe that it is the 'imaginary' time component that is switched off. The 'real' time aspect of the brain switches on, the 'unreal' time responsible for memory recognises the situation but the 'imaginary' time continues in dreaming mode and does not respond to the stimuli to switch on the waking up signal by for instance telling the relevant gland to produce cortisol. (The heart and lung function continues to operate under a much older order of brain activity, programmed to work continuously at all time.)
Doctors and psychiatrists might think of other conditions that could be explained by the three dimensional nature of time. Get in touch.
