Scientists still debate the exact mechanism, but the leading explanation involves a brief mismatch between two separate memory systems.

How Does Memory Work?
Memory is not a recording. Every time you remember something, your brain rebuilds it from scratch. Here is the real science of how memories form, stick, and fade.
Neuroscience
