In quantum physics, there is a topic on something called retrocausality, which addresses whether the future can affect the present and whether the present can affect the past.

In terms of deja vu and dreams, are they the result of future information being transferred to the present/past?

Actually, I'm wondering whether psychology and quantum physic are related in any way.

  • Welcome to Psychology.SE. First of all, I am not the one who downvoted your question, but I am at a loss to what or are trying to ask. The second paragraph seems incomplete and I am trying to work out how your question relates to the subjects covered in this site, especially when, as you point out, retrocausality is a quantum physics subject. Can you please edit your question to add clarity? – Chris Rogers Sep 10 at 7:50

Short answer
Déjà vu and dreaming are closely related to memory and memory formation. However, they have nothing to do with future events. The brain cannot recall what it never has processed in the past.

Background
Déjà vu is thought to be related to the tip-of-the-tongue feeling, in the sense that it is a memory phenomenon. It can occur when someone encounters a scenario that’s similar to an actual memory, but they fail to recall the memory. In other words, it's not an actual memory but an erroneous retrieval of a memory, if you like (sources: PsychCentral & New Scientist).

Dreams are basically stories and images our mind creates while we sleep. It has been proposed that dreams reflect biological processes of long-term memory consolidation. Consolidation strengthens the neural representations of recent events (i.e., their memories) and embeds these new memory fragments into older, existing memories. This also maintains the stability of existing memory representations in the face of subsequent experiences (Payne & Nadel, 2004). In sleeping rodents, for example, neurons in the hippocampus fire in patterns remarkably similar to those recorded during a previous maze-running session—almost as if the animals replay the experience in their sleep (source: Science Magazine).

In all, déjà vu and dreaming are indeed closely related to memory, and memory formation. However, they have nothing to do with future events. The brain cannot recall what never has perceived in the past. Hence, déjà vu experiences and dreams have nothing to do with what the future may bring, other than cases of pure coincidence.

Actually, I'm wondering whether psychology and quantum physic are related in any way.

There's no conclusive evidence insofar that quantum processes play a distinctive role in brain, although some hypothesis or another typically relating qubits (or entanglement) to consciousness seems to endure on the fringes.

Note that retrocausality is fringy even without involving the brain, as in not being strictly necessary to formulate entanglement.
