You draw the line, from a Christian perspective, by using scripture, intuition and reason to test the experience.

2 Corinthians 11:14-15 (King James Version)
14And no marvel; for Satan himself is transformed into an angel of light. 15Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
1 John 4:1 (King James Version)
1Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
1 Corinthians 11:31 (King James Version)
31For if we would judge ourselves, we should not be judged.
2 Corinthians 13:5 (King James Version)
5Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
Romans 12:2 (King James Version)
2And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Matthew 7:16-20 (New International Version)
16 By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles? 17 Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus, by their fruit you will recognize them.
2 Peter 2:1-2 (New International Version)
1 But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves. 2 Many will follow their depraved conduct and will bring the way of truth into disrepute.
