Daymare

Daymare is analogous to nightmare as it is the experience of a frightening or unpleasant fantasy during day time. Its use started in the 1700s when English speakers looked for an appropriate term for this kind of nightmarish experience while one is awake. This term was also used by Charles Dickens in his novel “David Copperfield” with the line, “a monstrous load that I was obliged to bear, a daymare that there was no possibility of breaking in”.

Psychologically, daymare refers to a phenomenon characterized by a panic attack, states of distress, or anxiety triggered by conscious fantasies.
