I dreamed that I was telling someone that Otto von Bismarck was to take me to a hospital appointment and for some reason I found that so funny I actually woke up laughing, not lol laughing but that half-silent wheezy whickering that makes you sort of fold up as if on a hinge, and you have no control of. Took me a while to stop setting off again.
That I can recall - never done that before. Go figure, Freud.
