That is why when we dream we are using our hand we are believing in a different perspective as opposed to waking up from our dream to find out that reality is far much bigger that the dream, thus we seek to doubt the dream. Thus the dream and reality all refer to the uncertain and certain analytical point of view. â€Å"They are on the one hand experiences of the ordinary, healthy mind, experiences with which no one could plausibly deny an acquaintance, and yet, on the other hand, they are comparable, in their extravagance and deceptiveness, to the delusions of insanity the narrator has just been considering.† †¦ I see plainly that there are never any sure signs by means of which being awake can be distinguished from being asleep.
