You may indeed have a ghost. Or you may have done it yourself, subconsciously. How? Because you, yourself, are a Ghost.
You are a spiritual being (ghost, soul, Holy Ghost, Holy Spirit, true self) who happens to have a physical, Homo sapiens body.
You were created in the image and likeness of the Father -- non-physical, spiritual and immortal source of creation. In other words, you have the ability to create. You also have the ability to bend or break the laws of physical reality. That's how Peter was able to stand on water, albeit only a few moments before doubt set in. That's how Moses was able to part the sea. That's how I was able to perform my own miracle during rush hour traffic in Los Angeles.
The Age of Miracles never ended. The type of confidence required is rare -- the perfection of confidence that Jesus tried to teach us. But like pregnancy, you can't be half confident and expect any of a miracle to manifest. Even at 99.999999999999% confident, you will still not be pregnant with faith to perform miracles; that's as good as zero percent.
The funny thing is, miracles are easy. If you "try" at all, you're working too hard. There is no "try." Like Yoda said in Star Wars, "There is only 'do' or 'don't do.'"
