spirits will interact with us if and when they so choose to. it all depends on the situation of the spirit, some do not even know that they are dead. there are tools that one can use to help with communicating with spirits. i DO NOT suggest ever using a ouija board. a pendullum is safer. spirits are people, too, therefore i do not approve of all so called "ghost hunters". i mean how would you like if someone came banging on your front door while you were trying to rest and wouldn't stop until you answered?
