Although, the paranormal is not a proven thing to some, I believe in it from personal experience.
I usually know who is on the other end before I pick up the phone to answer.
I know and have communicated with at least three loved ones, who I am certain are my 'guardian angels' , who have passed away: My step-father, my aunt, and a good friend of my father.
So you see, sometimes those 'gut feelings' that we have just might be a signal from those who protect you even though not on this planet anymore.
I have also met people in Church who have strong feelings/premonitions, and they don't think anything wrong with it.
And the way life deals out cards these days, it's good to know that you have your loved ones with you one way or the other.
Keeping an open mind is healthier than wearing blinders all your life - it makes it more interesting.
