Self-administered EMDR: using bilateral stimulation on your own
A free bilateral stimulation tool you can use in your browser — a dot that moves left and right, with optional alternating tones through headphones. Set the speed, set the length, and follow it with your eyes. Nothing to install, no account, and nothing you type is sent anywhere.
What bilateral stimulation is
Bilateral stimulation is rhythmic left-right input — visual, auditory or tactile. In EMDR it is used while someone holds a distressing memory in mind, and it is the component this tool provides. The approach was developed by Francine Shapiro in the late 1980s and is now recommended for post-traumatic stress by the World Health Organization, among others. Why the alternating input helps is still debated; the leading explanation is that tracking something while recalling a memory loads working memory, so the memory is recalled in a less vivid, more manageable form.
What this tool is, and what it is not
This is the bilateral stimulation part on its own. Full EMDR therapy is an eight-phase protocol with history taking, preparation, a safety plan and a trained clinician in the room, and it is not something anyone self-administers from a web page. What you can reasonably do alone is use bilateral stimulation for everyday stress, restlessness, a loop of worry, or winding down — the lighter end. Serious trauma belongs with a therapist, and this tool is a good companion between sessions rather than a replacement for them.
How to use it
Sit comfortably with the screen at arm's length, roughly at eye level. Follow the dot with your eyes, keeping your head still. Work in sets: thirty to sixty seconds of tracking, then stop and take one slow breath and notice what turned up — a thought, an image, a sensation, or nothing at all. Do not chase it. Start the next set and let whatever came up be there. Six to eight sets is a normal session. If you are using the journal, write one line between sets rather than during them.
Choosing a speed
Speed is measured in passes per second. Around one per second is the clinical standard for processing and it is the default here. Slower — half a pass per second — suits winding down, falling asleep, or anyone who finds the faster pace agitating. Faster than about 1.2 is rarely more effective and is often just harder to track. If your eyes are straining or you keep losing the dot, slow it down; effort is not the active ingredient.
When not to use it
Not during an acute crisis — if you are overwhelmed right now, grounding first is more useful, and there is a crisis kit on this site for exactly that. Not if you have photosensitive epilepsy or any condition where moving visual patterns are a trigger; use the audio-only mode instead, or skip it. Not as a way to work through major trauma alone. And if you dissociate — if you lose time, or the room goes unreal — stop the session and come back to the room: feet on the floor, name five things you can see.
What to expect, and when to stop
Emotions often rise before they settle, and that is ordinary rather than a sign something has gone wrong. What should not happen is that the distress keeps climbing set after set with no let-up. If that is what you find, stop — it is a signal that the material is bigger than a self-guided session, not that you did it badly. Finish deliberately: one slow set at a low speed, then a minute doing nothing at all before you get up and carry on with the day.
Common questions
- Can I do EMDR on myself?
- You can use bilateral stimulation on your own, which is what this tool provides. You cannot self-administer full EMDR therapy — the eight-phase protocol assumes a trained clinician, and the phases that make it safe are the ones you cannot do alone.
- Is bilateral stimulation safe without a therapist?
- For everyday stress and restlessness it is generally well tolerated. The caution is about the material you bring to it, not the dot: processing major trauma without support can leave you opened up with nothing to close it. Keep to lighter material, and stop if distress climbs steadily.
- How long should a session be?
- Ten to fifteen minutes is enough for most purposes, usually as six to eight sets of thirty to sixty seconds with pauses between them. Longer is not better; the pauses are where the noticing happens.
- What speed should I use?
- Start at one pass per second. Slow to half a pass for winding down or for sleep, and only speed up if tracking feels easy and unhurried. If you lose the dot or your eyes strain, that is the signal to slow down.
- Can I use it to fall asleep?
- Many people do, at a slow speed with a dim screen. Use the audio mode with headphones if the light keeps you awake, and set a length rather than stopping it by hand.
- Is it really free?
- Yes, and no account is needed. The session runs in your browser; what you write in the journal stays in your browser unless you choose to email yourself the summary.
