Is a ouija board a legitimate form of contacting spirits, I am curious to see if whether or not a simple board can be used to talk to people from your past or even summon demons. I'm fairly sure that Hollywood doesn't provide the correct interpretation of there use that is why I have come to this question in the first place.
It can be a legitimate means of communication -- granted, it is a matter of belief, and not verifiable fact.
That said, it is advisable to be prepared, and also to be specific in your callings. As some call it, using a spirit board irresponsibly is sort of like prank calling the spirit realm, and you never know who may show up.
Banish, cleanse, ward, and protect before hand. Cast a circle if it is your tradition to do so.
Be specific about whom you wish to contact.
Always be polite, invite and don't demand, thank the entity, dismiss the entity. Saying goodbye, establishing completion, and sending it away is important.
Avoid using it in a public way, or in a public place. It can be problematic if you are interrupted by people who either don't know/understand what you are doing, or disapprove outright.
Otherwise, it can be used pretty much anywhere. Though you might find that certain places would be more favorable to certain beings. For example, if you wanted to use the board to call on an ancestor. Like... say... a grandmother. Then you would have an easier time going to a place that she loved to spend time in. Her home, for example. Or her favorite spot at the park. Or some other location that would be significant to wither her, or your relationship with her.
