Precall (or Pre-Call) is a hypothesis developed by Sean O'Donnell of UCG, Galway, Ireland. It concerns the nature of time and memory, suggesting that we are capable of being time-symmetrical (remembering both the future and the past). This idea was developed in his 1999 book "Future Memory & Time: A New Skill of Mind", which he claims is a scientific and experimental approach to pre-call or future memory.

The author documents successful experiments showing that it is, in fact, possible to "remember the future" by experiments with card "guessing". The author's principal argument for skeptics is that we do not understand objective time enough at our current technological stage to disprove the hypothesis and that the facts of his experiments greatly back up his idea.
