Some may say energy is mass, and mass is a spirit but only if it has or ever had a preset form. Djin are said to have no form but i find this interesting as i always see them as black shadows in the shape of a person. It definitely depends on your opinion and how you look at things. Like mass energy takes on no form of shape however you can use it to shield yourself.. A spirit however has a form but the soul in side of the spirits orb would be mass as there is no definitive form until the spirit is no longer in the orb and formed into a shape or entered a body. Orbs have a form but inside is where the soul resides. The orb seems to be the vessel to carry the spirit to where it needs to go these are normally souls lost or ready for there new birth in search of a body to become reborn.

Residual Haunting
A haunting that has memory. The event sticks in the area time does exist for this haunting. The event just repeats itself.
