The frame is a metaphor, to mean that all reality is stratified through frames. We use the expression “frame” of mind, “within a certain frame”, someone has been “framed” (this is more difficult). Suppose you spend all your life with a mate and late in time, too late do anything about it, you discover that your mate has always betrayed you. All of a sudden your whole life is disqualified by this discovery, the discovery puts a frame around your past life. For me, to make an example, to discover late in life that all my pretending to be “normal” was useless, was a huge waste of efforts, disqualifies my life. There is a sieve, so to say, that divides blocks of you life, separates, stratifies experience, like the frame of a painting separates the painting from the wall.
Being “framed” happens when someone plagiarazing you, or cheating you for exploitation, keeps you in a interpretative frame that is delusionary or misleading. I took years for me to understand that psychoanalysis was one of these misleading frames. Now I can read the relationship with friends, women, parents etc, in a totally different frame. Too late, though.
Sometimes someone, the holder of the frame, is cynic, sometimes is deluded himself and sometimes the holder is halfway in between the two situations.
