Note
Older religious writing leaned on this verb. Richard Baxter says faith may realise salvation to the soul; the anonymous Life of Mr. Henry Dorney has true faith realising things absent, remote and future. In Defoe's Farther Adventures of Robinson Crusoe, something imagined is so realised that it is taken for true. Presenting a thing to oneself this way is now archaic, though a novel or stage set can still realise a scene.

Note
Recorded from American English and now obsolete: to realise something was to meet it in real experience, to live through it rather than imagine it. Because the becoming-aware meaning and the vivid-sensing meaning also turn on what feels real, an old sentence can be hard to assign to one of them. Present-day English says experience or go through.
