Distinguishing Ghosts from Spirits

In all of the books I've read from other mediums or ghost investigators, most don't distinguish the energies between ghosts and spirits. Most call them all "spirits" but I felt it important to make  distinction, so I call Earth-bound energies "ghosts," and those that crossed into the light, "spirits."
  Both are beings of energy and personality, but ghosts choose to stay here on Earth or get stuck here for some reason (which I explain in my books "Ghosts and Spirits: Insights from a Medium,(http://www.amazon.com/Ghosts-Spirits-Insights-From-Medium/dp/1602645132/ref=sr_1_1?ie=UTF8&qid=1352336292&sr=8-1&keywords=Rob+gutro)  and "Lessons Learned from Talking to the Dead." (http://www.amazon.com/Lessons-Learned-Talking-Dead-Volume/dp/1475033214/ref=sr_1_2?ie=UTF8&qid=1352336292&sr=8-2&keywords=Rob+gutro)
   Ghosts are all about "location, location, location." They inhabit places they enjoyed during life on Earth, or they're stuck in a place where they died (like a prison or a car accident site).
   Spirits on the other hand have joined the energy of the cosmos, or Heaven, or into the light - call it what you will.
   Both draw on physical energies and emotional energies. Ghosts emit negative energy, and are fueled by physical energy as well as negative emotional energy, like fear and anxiety. Spirits, however, are full of positive energy, and are fueled by postive emotions like love, faith and hope as well as physical energy. I explain those in detail in my books as well. One thing that spirits can't do that ghosts can, is that spirits can appear in your dreams. That's how you know they've crossed over.
