mine come and go, not sure why. what helps are

-to pray directly to God for assistence to move those to the light
-stop meditating if you do that, they see you as a glow and they come, both good and bad. Try if you can to not interact with ghost during your dreams, this can be hard as it goes telepathically and because in the dreams one is relaxed but if you can, do that.
-get the vibrations high, that way you sort of lift the energy of the home up from the ground. The ground symbolise then the low life energy, closest to our realm here on earth, negative emotions
-could there be something on your aura? meaning unsorted trauma, to use an example sexual assault? have you kept old pain to yourself and not dealt with it like you should? then now is the time to do that to heal the aura.
-don't think about them, the spirits. don't give them the satisfaction of your fear or any other emotin, thought, that only make the connection stronger and the energy of those goes up and more activity will start.
-create a protection shell, wall around you, coudl be a circle of light but basically anything to make a shield.

almost everything of the above i have learned through other members on the forum who were so kind to help.
