All dreams that there are, ever were or ever will be can be divided into three categories:
A) Dreams dreamed when asleep
B) Dreams dreamed when awake (also known as delusions)
C) Dreams dreamed in the instant between being awake and falling asleep (also known as hypnagogic dreams)
Each of these categories can be further subdivided into subcategories, enumerated below.

49) Dreams in which you dream about waking up from a dream and analysing that dream
50) Dreams in which you dream that you are back, for the first time, in your home town in your Mother Country, from which you migrated when you were still a child, back in the old flat in the apartment block you used to live in; and you go outside into the front yard where you used to play, hoping to see people from your past, although you realise that much time has passed and that they would have changed by now and grown older, and so might not be easily recognisable; but all you see are little kids playing outside who wouldn't know you and whom you wouldn't know; and so you go back to your old flat and look at the things in it, and try to recapture the magical feeling of gone childhood

56) Dreams in which you dream that it is August 31, 1939, and you have a lover who also happens to be the lover of Adolf Hitler, and so, in effect, you share her with one another, and you shudder to think that you kiss the same lips that he kisses; and you then invite him for dinner to your apartment and you ask your paramour to try to convince him that war can still be avoided and that it is still not too late; and you then walk out outside for some fresh air and see a lot of Russian soldiers around and you scream out to them "Hitler is here!" in English, German and Russian, breaking the tacit agreement that, by being your invited guest, he should not have been betrayed; and the soldiers all rush to seize him, and he runs away with the speed of a champion sprinter, and they chase him around a sports ground and finally capture him in a giant pickle jar; and as soon as he is caught, a small dilapidated building that is standing next to the stadium is instantly transformed into a huge, futuristic looking architectural structure and you realise that with the dictator apprehended and subdued, World War II no longer happened, the time line of history has changed and thus, without the destruction, technology and society progressed much further, and you also realise that by your action of informing the soldiers of the tyrant's presence, you have erased your old life, for in the new time line, no one knows who you are and you have no relatives, and you will have to start your life all over again; and you then take a walk around the shopping mall, observing how this alternative Universe is different from your old world, and how there seems to be a lot more technologically advanced products around and how things in general appear to be brighter and somehow more innocent; and someone invites you to come to a rap concert that is about to start, and so you sit down to watch the rap artists coming on to the stage, dressed in 18th century style clothes with powdered wigs, performing the most schmaltzy song and dancing a kind of a minuet, and you think to yourself 'So this is what rap is like in this time line!', and you then realise that as there was no world war in this alternative Universe, the anger, the cynicism, the breakdown of social relations caused by it in the old time line are not present here, the traditional values of the dignity and value of human life are still intact, humanity hasn't become scarred by the cataclysm of war and things are still innocent and sweet, just the way they used to be before the war; and you then go to a cinema and find yourself sitting next to your lover, or at least next to the person who was your lover in the old time line, and who doesn't know who you are in this time line; and the movie that is being shown is about the capture of Hitler, an event that you yourself had engineered and played a vital role in; and the movie comes to a point at which the evil tyrant is captured, and consequently the whole time line shifts and history changes; and you look at the person sitting next to you, your lover from the old time line and wonder if watching these events will bring her any memories of you or any memories of how history had changed

------------------------------
(1) These subcategories are not mutually exclusive and may overlap
(2) It should be noted, more as a curiosity than anything else, that by a truly bizarre coincidence the taxonomy of nocturnal dreams and the taxonomy of climates partially overlap, for the categories 29 to 35 of dreams correspond precisely to the way climates are categorised according to the Köppen-Geiger climate classification system
