Culture & Language

Also in: Schlafbrief (Deutsch) · sueñocarta (Español) · sommeillettre (Français)

A message composed in a dream to someone who cannot receive it, unsent and unsentable.

The sleepletter is written with total conviction to the dead, to the estranged, to a person who does not exist. Its text is perfect in the dream and gone by the alarm. Some dreamers wake with the feeling of having sent it, and spend the morning wondering why there is no reply.

Etym. — sleep + letter — the correspondence that happens only in the night postal system; poignant, precise, and not a standing phrase.

Rel. — dreamorphan · dreamhomesickness
