i had one christian ex colleague
who told me whenever u feel evil spirits around u, juz mention
'Jehovah' (not sure about the spelling) and the spirits will be
scared. duno how true la, coz i never believe in christianity, no
offence to christians.
but my dad ever told me that if i ever see one right in front of
me, juz walk backwards 3 steps and it will be scared of u. but so
far all my encounters.. they juz appeared and did not do harm to
me.
