Demons are out to possess you however they can and they're not averse to tricking people into inviting them in. 

They will tempt you with any tricks they can - ouija boards, seances, spiritualist meetings, tarot cards, wicca, drugs, alcohol, meditation, etc.....you name it they have it covered!

We have to guard our minds!  We are a precious commodity to God and the devil knows it.  The one way he can hurt God the most is by hurting us.

Matthew 12:43-45

⁴³When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none.

⁴⁴Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished.

⁴⁵Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
