It's not at all interesting, or complex. It's your imagination and quite possibly the onset of schizophrenia. Not to mention science has already shown it (ghosts and the "paranormal") to be impossible.

The LHC Disproves the Existence of Ghosts and the Paranormal
If we want some sort of pattern that carries information about our living cells to persist then we must specify precisely what medium carries that pattern and how it interacts with the matter particles out of which our bodies are made. We must, in other words, invent an extension to the Standard Model of Particle Physics that has escaped detection at the Large Hadron Collider. That’s almost inconceivable at the energy scales typical of the particle interactions in our bodies.
