what is a psychic attack?

I cant tell by experience but this is what i found on internet.........

There are intentional psychic attack
and unintentional psychic attack.
Both and either of these psychic
attacks carry negative energies and
will weaken you once being
absorbed into your physical, mental
and emotional body.

Intentional Psychic Attacks

More
likely black magic are mental
domination deliberately done by
high skilled black magicians or
sorcerers with the intention of
causing hurt. Some of these psychic
attacks or black magic spells are
reversible and those which are not
reversible can lead to death
eventually.

Unintentional Psychic Attacks

Are
not intended to inflict harm, but due
to your avoidable and unavoidable
presence in these negative
environment, your aura will
unconsciously absorb these negative
energies.

There are as many methods of psychic attacks as there are thought forms swarming around in your head.
A few common ones:

1. Attack through dreams.
2. Charging an area (common to the victim) with negative energy.
3. Directing negative energy at them using various foci.

Some experiences you have when under attack are:
1. Headaches.
2. A loss of memory and forgetfulness.
3. Lack of energy, tired.
4. Unexplained disrupted sleeping cycles.
5. Other people treating you differently.

How to protect yourself from psychic attack:

1. Seal or consecrate your room so that it acts like a filter while you're sleeping.
2. Shield yourself using meditation or some other internal method.
3. Use some sort of foci to block certain people you know may attempt to attack you.

There are a plethora of books on the subject.
