One thing I've found that I can do that I really enjoy is rereading my own writing, earlier stories and novels especially. It induces mental time travel, the same way certain songs you hear on the radio do ... the whole thing returns, an eerie feeling that I'm sure you've experienced.
Philip K. DickHuman has always striven to retain the past, to keep it convincing; there's nothing wicked in that. Without it we have no continuity; we have only the moment. And, deprived of the past, the moment - the present - has little meaning, if any.
Philip K. Dick"Do you have information that there's an android in the cast? I'd be glad to help you, and if I were an android would I be glad to help you?" "An android," he said, "doesn't care what happens to another android. That's one of the indications we look for." "Then," Miss Luft said, "you must be an android."
