Psychic shields are constructions, made of prana/chi, and programmed for a specific purpose. Generally, they are used to prevent intrusion of chaotic or destructive elements within the shield builder's bodies. They are an important addition to healing techniques, as well as an extremely robust protection against all kinds of potential threats.
Generally, ghosts are harmless and just want to discuss. Talking to them without fear is often enough to have them go. Asking them to leave should do the trick. And for some demons, the same procedure applies. In some cases, if the spirit is particularly persistent, you may inform them that they will only find peace and love if they go into the next world while focusing on reaching those. They will not find it here - they have died and will find a better place by moving on. This is reported to work in many situations.
A first good reflex when dealing with dark entities, is to create a psychic shield. In order to do this :
What this does is co-create a thoughtform and charge it with the combined energy of your patron and yourself. Thus, it does really cast a psychic shield around you. Which suffices for most cases.
Worst cases are true telekinetic attacks, such as in the case of Incubi and Succubi, feeling them at night sitting on your chest. In any event, you can and should also create a psychic shield when you feel threatened this way, or simply demand a nightly protection in prayers.
The most important thing is to pray in a heartfelt way, to really believe in what you are asking and place your love and energy in it.
Milder cases include nightmares, manipulation of your shadow, or static on your phone line, difficulties with your computer. In any of these situations :
Last but not least : if you really, really, really feel like attacking them, which I do not recommend because it yields escalation and you have to be certain you can handle it, then cast all of your anger, your fury, into a "ball of energy/prana" which you will send at them. As I said, if this is extremely strong, it can damage them or push them away, else it is food again, and yields escalation.
In any event : trust the power of love and co-creation. Do not fall for despair. Do not fall for fear. These are illusions and feed the darkness. When you combine your intentions with those of a higher spirit, praying in a heartfelt way, co-creation occurs - enabling you to easily achieve the desired outcome.
