Instinct makes you turn around and walk away, paranoia makes you keep looking over your shoulder.
Instinct is the first feeling you get and it's usually right.
Paranoia springs from instinct or nothing and keeps going round and round in your head conciously.
With instinct one is cool ,calm and smart enough to keep silent , paranoia is just Fear of Fear it's self on any subject .
Oprah did a show on this... The mind takes in almost infinite amounts of information but we only "knowingly" process a tiny fraction of that information to get around in our world. Often the information we process unconsciously might have taken in factors that we didn't catch consciously. Women especially, because of all the communication nuances women are better adapted catching (85%-90% of communication is nonverbal) might pick up on inconsistencies in communication that logic may dismiss as unfounded. There just isn't any "tangible" proof . Instincts, however, send up flags because of these inconsistencies, telling us to remain alert. A fun show to watch is "Lie to Me" the main character is trained to watch for signs that we as human beings already know but never broke this knowledge down into a science.
If your not paranoid your not paying attention
If you're questioning that it is paranoia then it must be but instinct is that feeling you get when you KNOW that something is amiss but cannot provide evidence.
Always trust your gut instinct,it's nature's way of saying ''whoa! Hold Up!''.....
