The Matrix in a Matrix (MIAM) was a popular fan speculation which circulated after the release of The Matrix Reloaded in discussions online. The theory was that the Real World was not actually real, but rather another level of the Matrix simulation: i.e. the Redpills were always remaining in the Matrix, and everything regarding their Extraction, Zion etc were also a simulation. This theory expected a possible major turnover in the next movie, The Matrix Revolutions, which would eventually reveal the truth.
