Are Ouija Boards Dangerous? YES

A resounding YES! Ouija boards are an invitation to the earth bound spirits and restless energies to 'come on in!'. Even playful attempts for a message on a ouija board are a 'no no'.
It's reckless, dangerous and harmful. STOP! WARNING!
Yes you've seen angel boards and other kinds of 'positive' boards out there which guide you to surround yourself with white light and sea salt etc. before moving within your protective circle and asking for spiritual contact.
THE BIG DIFFERENCE IS THAT THESE OTHER BOARDS ARE MEANT TO CONTACT ONLY THE HIGHER ENERGIES WHO HAVE YOUR BEST INTEREST AT HEART: SPIRITS WHO HAVE CROSSED OVER THROUGH THE LIGHT, YOUR GUIDES AND THE ANGELIC REALM.
The protection you surround yourself with is meant to keep out negative and earth bound spirits who jump on any opportunity to MANIFEST through a host (that host is the seeker on the ouija board!).
Reckless ouija board playing is an invitation to something NOT HEALTHY for you. It's basically saying: "Come and possess me! Come manifest in my home!"
If earth bound spirits and demons come through, then your protection didn't work. Duh.
Ouija boards are like doorways through the protective veil which exists . . . for earth bound spirits who haven't crossed over and/or refuse to, AND for any diabolical/demonic beings who are near.
Don't invite unwanted bad luck in to your life (and to the lives of your children, friends and family)! Please please know the danger is REAL.
