Trauma, perhaps only when it happens before a certain age, can open a person’s aura up to the negative energies of others and this can be debilitating for that person. There were times in years past if I went to a social gathering it would take me three days afterward to recuperate from feeling the onslaught of the troubles people carried around with them.
I’ve known four people whom, if I had contact with them, I began to feel suicidal. One of these people is now deceased but he had a horrific childhood with an alcoholic father.
Trauma can also open people up to the paranormal and in some societies this is considered desirable.
