After Life

What can rationally be conjectured about events following death for the experiencer?
Since the source of awareness and feelings is DNA and since DNA continues to function after death for some time (hair continues to grow), we can presume the dead are in the ghost state and are following events: the funeral, the burial, etc. The best description of this period that I am aware of is provided by Thornton Wilder in his play, "Our Town".
What can be said about this state? From all reports it is very pleasant, no sense of body would remain, no sense of time, no sensual input at all. The only memory would be that which resides in DNA. What would that be? We have several hierarchical levels of memory, high level, the results of consciousness, presumably resident in the brain; short term, also a brain function; long term may reside in DNA; probably self identity also resides there. Our state of being would be similar to that of sleep, without sensual awareness. Our thought would be the dream state, not dissimilar from the waking state except that we think in terms of large symbols, rather than small ones. We aren't so much thinking as visualizing, things occur but there is no sense of time. It would be that out of body experience that is often reported. We would do well to elliminate evil spirits (complexes) before death, otherwise they will also be there.
This state of affairs can be expected to continue for some time and a gradual disconnection from the living would occur. We would retain the spiritual awareness we had achieved during life. No further achievement could occur in death which may lead to a need to reincarnate as the Buddhists believe. Anyway, the ghost state would obtain until the DNA breaks down, which could be a long time in human terms or a short while. Presumably, in the case of cremation it would be short, in the case of burial it would be much longer. Possibly the practise of mummification is intended to prolong this period for as long as possible. This is probably the actual reason for the pyramids. The Pharoahs hoped to maintain the ghost state until the astrological conditions of their birth recurred, this takes 26,000 years, I believe. So, the problem was to avoid grave robbers. Obviously, they failed. Or, maybe they didn't, depending on the keepers of the relics in Egypt.
Beyond this lies the deep sleep state, probably. The Hindus declare they have some knowledge of this state. Beyond that lie questions.
A warning would probably be appropriate here. One of the great things about consciousness is its control over fantasy. After death, no conscious control, which will mean that fantasy has control. Fantasies can produce any emotion from bliss to terror. The Tibetan and Egyptian Books of the Dead declare that terror is the motivating force behind most reincarnation. That only great spiritual achievement can expect to avoid terror. In fact the above books are intended to instruct devotees in methods of avoiding this pitfall.
This is not out of the question. This is exactly why two people I know had to give up marijuana. They arrived at that state in which they could not control their fantasies. So, it is well to die of old age after one has had the time to rise above fear. Those unaware of fear inspiring fantasies are protected by their lack of knowledge. Once that awareness arrives the only hope is to rise above it. This requires one to overcome attachments to life, which are the source of the fantasies. Love of power, money, sex, etc.
