Please share your spookiest true stories with me

A friend and I were visiting historic Savannah, GA...considered to be among the most haunted cities in the US. I tend to be sensitive to the paranormal, and often get a strange, almost light headed feeling when something is about to occur. My friend and I went into a corner coffee shop, and I immediately felt that sensation. I went to the counter and ordered a cup of coffee. As I waited, I noticed a very elderly woman...late 80s to early 90s, with a gaunt face, using a cane, slowly walking toward me. As the staff member handed me my cup, I looked up and the woman was glaring at me. She had what appeared to be an antique cane, with a large purple cut crystal handle. Her hand shook side to side as we locked eyes. This really grabbed my attention. I walked over to the opposite counter for the cream and sugar, turned and looked back toward the woman, but I didn't see her. I had only turned my head away for maybe 10 seconds. I looked around the seating area...no sign of her. I even went outside and looked up and down the street. I turned to my friend and asked where the woman went, but had no idea who or what I was talking about. There was no way the elderly woman could have walked away that quickly. Seems she had vanished.
