To read about "filosophy" as one of the "major phetishes" here is very "phunny" for me, and in order to top every "filosofer" here, I would like to mention several facts of which we do not know if they might one day be "alternative" ones, but I have read a lot about all these facts and possibilities and if I only had enough money, I would do my own research about that:
1. We cannot be sure how many dimensions there are in this universe. OK, we all know the three dimensions of the space in our wardrobe but when we add time to the three spaces in our washing machine during the "action" there, socks can suddenly disappear!
So, the fourth dimension of "time" seems to have some unexpected characteristics. Maybe, time itself has more dimensions than only one because throughout human history, there are stories of "precognitive dreamers" who could see the coming events or catastrophes of near future during the coming 24 to 48 hours.
a) According to several different ancient sources (so we can "almost" take this as a historical fact), Calpurnia tried to convince her husband Caesar not to go to the senate on the "ides of March" in 44 B.C. because of her nightmare in the night before. Unfortunately, he did not believe in dreams at all.
b) Hans Berger, the German inventor of the EEG (electroencephalography) had his own special reason for his scientific work on the very weak electrical current in human brains, because his sister dreamt all details of a dangerous accident of him at exactly the same time when it happened. She was waking up from her dream about 50 km away from the place of the accident, insisting that her father should send a telegram to ask about her brother's accident. Hans Berger tried to find out all his life how the information of his life-threatening accident might have been transferred to her. He thought it must have been transferred via electricity but he never found a real scientific proof.

2. So, when you take "precognitive dreams" as a possibility or reality, where do they come from and who or what is sending them?
Do they come from an additional dimension in which time is flowing like a river which can flow a bit backwards when there is a sudden obstacle in the river?
In some of such historical dream stories, relatives or friends who have already died a few time ago, are appearing in order to warn the endangered persons.
Shall we take this as a possibility of "life after death"?
We cannot be sure but we can also not exclude it.
3. In any case, the scientific researchers of the so-called NDE's (Near Death Experiences) found many, many different stories from different cultures with many different "imaginations" which seem to differ from one cultural "preset" to the next one. But really all of them had the feeling of a "peaceful happiness" in the moment of "clinical death" and many told stories of meeting family members who passed away before, even some who introduced themselves because the persons with such an NDE did not know any relative because of being an orphan.
OK, even if we think of this as a nice personal wishful thinking in the moment of our death, why should nature burn down such a nice firework of illusions in the moment of death when it could also simply switch off the lights?
There is no necessity for nature of organizing such a bunch of nice illusions and fireworks in our subconscious before our death ... except that there really is still something after our material life and death.
(Mhm, I should add that the NDE-researchers usually asked "normal" people for their NDE's. Maybe, we are not all "normal", because I know also one single different story of a NDE of a bank robber, who had to live through his last robbery via the eyes of his victims there. This might be the worst hell of all imaginations and if it is an invention by the researcher, it is one of the best I have ever heard of ...)
