I have not seen or spoken to a ghost, but I believe that I have heard one. My grandparents slept in the same bedroom, but in separate beds. Immediately after my grandmother died, my sister, brother, and I decided to take turns sleeping in her bed in order to keep our grandfather company in his deep grief. On the night of my turn, I lay in bed listening to my grandfather's snoring. After a time I began to hear footsteps coming up the stairs toward the bedroom. These were not ordinary footsteps, but very slow and labored stopping at each step before continuing....exactly like the footsteps of my grandmother. I was about 14 years old at the time, and I was petrified. I also became paralyzed with fear and could not move. When the footsteps reached the top of the stairs, I closed my eyes and could not look. Then all was quiet, eventually I fell asleep. I later came to find out that my younger sister and brother had the same experience on their night to stay.
So, yes I believe in ghosts. There are too many things in this world that science can't explain. And yes, I would be willing to visit a haunted location.
