Can you give us a tutorial on where in the body the different types of spirits typically attach?

The chakras are the major sites, and the reason is that these are energy scavengers and they will attach at all the chakras, all of the major chakras, and if there is an allowance for additional meddlers to join the fun, even some of the minor chakras will be targeted. So that is the major location. The lost soul energies can be anywhere in the body, as you have witnessed yourself. They will avoid the chakra regions because those are usually taken and there will be a battle for them if they should intrude. The lost souls are often in the torso but can extend into the extremities, and the spirit meddlers are on the chakras. They can occupy any layer of body energy and energy from the tissues themselves, but they will usually stay in the chakra regions because they do not want to give up the high-voltage current, so to speak, and leave that site unattended as it might be claimed by a competing spirit.
