"Sometimes you dream strange dreams, impossible and unnatural; you wake up and remember them clearly, and are surprised at a strange fact: you remember first of all that reason did not abandon you during the whole course of your dream; you even remember that you acted extremely cleverly and logically for that whole long, long time when you were surrounded by murderers, when they were being clever with you, concealed their intentions, treated you in a friendly way, though they already had their weapons ready and were only waiting for some sort of sign; you remember how cleverly you finally deceived them, hid from them; then you realize that they know your whole deception by heart and merely do not show you that they know where you are hiding; but you are clever and deceive them again - all that you remember clearly. But why at the same time could your reason be reconciled with such obvious absurdities and impossibilities, with which, among other things, your dream was filled? Before your eyes, one of your murderers turned into a woman, and from a woman into a clever, nasty little dwarf - and all that you allowed at once, as an accomplished fact, almost without the least perplexity, and precisely at the moment when, on the other hand, your reason was strained to the utmost, displaying extraordinary force, cleverness, keenness, logic? Why, also, on awakening from your dream and entering fully into reality, do you feel almost every time, and occasionally with an extraordinary force of impressions, that along with the dream you are leaving behind something you have failed to fathom? You smile at the absurdity of your dream and feel at the same time that the tissue of those absurdities contains some thought, but a thought that is real, something that belongs to your true life, something that exists and has always existed in your heart; it is as if your dream has told you something new, prophetic, awaited; your impression is strong, it is joyful or tormenting, but what it is and what has been told you - all that you can neither comprehend nor recall."
- Fyodor Dostoyevsky
