[Erin Pavlina]

It's like being a flame and wondering why you're attracting moths. Negative, fear based entities are attracted to light. Your flame may be open and inviting instead of guarded and enclosed. Work on controlling your energy (do some chakra work).

To answer your other question about why you don't get in contact with positive entities... raise your vibration to meet them halfway. Negative entities are easier to detect because their vibrations are lower. Positive beings have higher vibrations. Change your frequency and you'll change what you attract.
