I’m sure you could play around with @Amaris_Bane’s technique for creating an energy filter. I believe there’s also a method for that in Psychic Witch… 
let me run and check 
I was right! Here are a few different methods you might find helpful. These also come from Psychic Witch by Mat Auryn 
Exercise 8 - The Psychic Dimmer
One of the most challenging obstacles for the sensitive person is learning how to control the constant input of information and even mute it at times. Taking on the energy of others is draining and leaves us susceptible and vulnerable. Part of mastering the self and psychic senses is learning how to create boundaries and figuring out what is yours and what is from others. The following is a super handy technique used to take control of the situation energetically. This can also be used if the psychic information you’re receiving is too quiet and you want to increase it, or if you’re doing meditation, psychic work, or energy work and the external energy is too invasive or “loud” and you’re having trouble relaxing and concentrating. This is a technique that I learned from Irma Kaye Sawyer that I’ve adapted.
Begin by taking a few deep relaxing breaths. Envision a light dimmer switch before you. This light dimmer switch increases or decreases psychic sight and volume. Just like a dimmer switch or a volume knob, if you turn the knob to the right, the information increases, and if you set the knob to the left, the information decreases. Affirm this mentally to yourself. Take a moment and discern whether you feel you perceive energy too much or too little. With intent, turn the knob in the appropriate direction, willing the energy bombardment to increase or decrease.
Another variation of this technique is to see a faucet above you filling your aura with psychic information. Just like the dimmer, see a faucet handle before you. Affirm to yourself that this faucet can increase or decrease the flow of psychic information filling your auric field. Take a moment to discern whether you feel you perceive too much or too little psychic information. With intent, turn the faucet handle in the appropriate direction, willing the energy bombardment to increase or decrease.
The Breath of Life
Breath is the bridge between the energies of the external world and the energies of your internal world. Breathing unites the internal and the external, creating a connection and circuit of energy flow. The word “spirit” comes from the Latin word for breath, which is spiritus, and was often used figuratively to refer to the spirit. The idea that breath itself is life force has parallels in various cultures, where it is known as prana, ruach, mana, telesma, chi, ki, numen, orgone, pneuma, od, and odic force.⁹ By working with our breath, we are working directly with lifeforce energy. Certain types of breathwork can cool down and relax the body and mind, while others can warm up and excite the body and mind, by changing the speed of the body’s rhythms.
Conscious breathing can help cultivate a deep-rooted connection with and enjoyment of life. By working with our breath, we can achieve more advanced states of meditation and consciousness. Since breathing is something so subtle and usually automatic, by tuning in to it we can strengthen our mind’s ability for concentrating and perceiving things that are of a subtler nature.
Exercise 43 - Foundational Shielding and Protection
Now that we know how to cleanse our energy, this is the perfect time to learn how to shield ourselves. With shielding you want to feel completely secure and confident. We will explore a foundational practice of shielding and different ways to alter that shield to be appropriate for what you’re doing. Sometimes you’ll want a shield that completely stops the flow of any energy coming in and out, but this can also completely mute psychic perception. At other times you’ll just want to filter out energy that is aggressive or negative, and this is usually my go-to when it comes to shielding. Figuring out which type of shield you need takes discernment, so trust your intuition. This foundational shielding should be a daily shielding practice; how you enhance it is up to your circumstances.
Tune in. Envision a brilliant white light a few feet above you. Verbally or mentally affirm:
“Spirit above me.”
See it begin to descend as a column of light around your body, down to a few feet below you. Verbally or mentally affirm:
“Spirit below me.”
The light comes up from below you and rises a few feet in front of you at chest level. Verbally or mentally affirm:
“Spirit before me.”
See the light meet the point above your head where it started, where it then descends a few feet behind you at chest level. Verbally or mentally affirm:
“Spirit behind me.”
The light moves counterclockwise until it is a few feet on your right. Verbally or mentally affirm:
“Spirit on my right side.”
The light continues to move counterclockwise until it is a few feet on your left. Verbally or mentally affirm:
“Spirit on my left side.”
It continues its counterclockwise movement until it reaches the point behind you again.
See all six points glow around you. The light begins to shine so brightly it forms a bubble around you. Verbally or mentally affirm:
“Spirit around me.”
Visualize the glowing filling your body as if you were an empty vessel. Verbally or mentally affirm:
“Spirit within me.”
Take a few moments to feel this light above, below, before, behind, on your right, on your left, outside, and within you. Then verbally or mentally affirm:
*“Spirit protects me. Spirit blesses me. Spirit heals me. Spirit guides me. *
I am, I always have been, and I always will be One with Spirit.”
Exercise 44 - The Filter Shield
Perform the Foundational Shielding and Protection exercise. Take a moment to feel the white light all around you, strong and vibrant. Envision a silver filter forming around the outside of your aura. Visualize it like a mesh strainer made of pure silver light. You can let go of the imagery of the silver filter knowing that it’s still there doing its job. Now repeat this process with a golden filter. Know that it will prevent negative energies from entering and allow energies that are positive to come through. You are not cut off from all the energies around you, but they will be filtered before they reach you and your energy field. State out loud or mentally:
“By lunar and solar
Opposites and polar
Energies that harm and wilter
Cannot pass my magick filter.”
I’ve not personally used these methods yet but I’ll be trying them eventually! I did make it through several of the beginning exercises and they’re pretty solid!
