mind's eye, in my

mind's eye, in my

In my imagination. This figure of speech dates from the early fifteenth century. Thomas Hoccleve used it in De Regimine Principium (1412): “Haue often him byfore your myndes ye.” So did Shakespeare in Hamlet’s statement to Horatio that he thinks he sees his dead father: “In my mind’s eye” (Hamlet, 1.2).
