My mother who is 72...has been hallucinating... seeing people and an occasional spider. She clearly sees them and even hears them talking. If she goes near them they dissapear. She is healthy and taking no medication. What could this be? It had been going on for 3 days.
the brain is a mesh of tens of millions of synapses and capable of 10s of 1000s of functions at once. tumors, cancers or anything in the brain can make a million wrong connections. has she been receiving treatments for any problems
