Maurice Merleau-Ponty

To perceive is not to experience a multitude of impressions that bring along with them some memories capable of completing them, it is to see an immanent sense bursting forth from a constellation of givens without which no call to memory is possible. To remember is not to bring back before the gaze of consciousness a self-subsistent picture of the past, it is to plunge into the horizon of the past and gradually to unfold tightly packed perspectives until the experiences that it summarizes are as if lived anew in their own temporal place. To perceive is not to remember.

The men that I see through a window are hidden by their hats and coats, their image cannot be imprinted upon my retina. Thus, I do not see them, I judge that they are there.

Just as the faithful in Dionysian mysteries invoke the god by imitating the scenes of his life, I too call forth the visitation of sleep by imitating the breathing and posture of the sleeper.
