For some people who suffer with trauma, therapists use “resource installation,” a technique that is part of an eye movement desensitization and reprocessing (EMDR) program. Basically, instead of trying to push away distressing experiences, patients are asked to zero in on a few happy, sensory memories where they felt strong, safe, and supported. At the same time, they’re told to close their eyes and move them back and forth, rhythmically, like what happens when you sleep. The theory goes that these eye movements cement good memories in your mind, according to The New York Times.ae0fcc31ae342fd3a1346ebb1f342fcb “We all have resources within us, such as memories of comfort and safety, experiences of being powerful and courageous,” writes Laurel Parnell, PhD, an expert in EMDR, in her book Tapping In. “These memories, qualities, and images are stored in our body-mind network and can be accessed, activated, and strengthened.” There are three main ways to do this. The first is to focus on positive personal experiences where you felt self-acceptance, courage, compassion, or any other empowering trait you might have. You can also use a peaceful symbol or dream that resonates with you. The most effective method, however, is to reminisce on soothing memories or loved ones. Then, close your eyes and consider all the senses of the scene, person, or symbol: What do you see? What do you hear? What do you smell? What emotions do you feel? As you process everything, start shifting your eyes back and forth like a metronome. It may help to slowly tap your fingers in time with each movement. Do this for a few sets, or until the image is clear in your mind and you feel calm. Though it’s not required, journaling afterward can be beneficial as well.
