there are electrical synapses in the brain that form our conscies our memories our personality and so on
Yes and no. These synapses aren't purely electrical, but biological.
This is what you're talking about.
it is also understood that a supernatural presence can emit EMF
That's not really "understood" but "commonly believed" as there is no evidence for supernatural presences to begin with.
the synapses retain information after the body has passed on
Here's where your reasoning breaks down.
use energy from the sorrounding world to take shape
How would that even work?
this theory states is that spirits are electrical enomlies that have a personality and interact with the physical world
Basically, A + invalid B + C with an unknown component = ghosts? Either way, you're making a lot of jumps.
also spirits will only interact with certain people
Which just makes the claim of them existing even more unbelievable.
for example i have a and she is constantly tormented by spirits she is small and has emotional problems
Have a...what? Daughter? Sister? Either way, don't you think being tormented by "spirits" she sees is more likely to be signs of some psychological illness...especially in light that no one else around can see them?
attach to that emotional energy
Emotional energy? What is that? Do you mean like an aura, because those are just as unproven as ghosts.
