the nightly obliteration of being

from Gaston Bachelard, The Poetics of Reverie (1960) trans. Daniel Russell (1969)

The night dream (rêve) does not belong to us. It is not our possession. With regard to us, it is an abductor, the most disconcerting of abductors: it abducts our being from us. Nights, nights have no history. They are not linked one to another. And when a person has lived a lot, when he has already lived some twenty-thousand nights, he never knows in which ancient, very ancient night he started off to dream. The night has no future. 
...
We become elusive to ourselves, for we are giving pieces of ourselves to no matter whom, to no matter what. The nocturnal dream disperses our being over phantoms of unusual beings who are no longer even shadows of ourselves. The words "phantoms" and "shadows" are too strong. They are still too well attached to realities. They prevent us from going as far as the extremity of the obliteration of being, as far as the obscurity of our being dissolving into the night.
