"These "suckers" are not bad people, most of them are not aware on a conscious level that they are doing what they are doing. Still, their unknowing actions can play havoc with anyone who leaves an energetic opening for this type of thievery. It is important for us to be aware that we may be susceptible to having our energies stolen from us and learn ways to protect ourselves. The harm in a psychic attack is that there is no fair exchange of energy and therefore one feels depleted while the other becomes energized."
