What Does a Seizure Actually Feel Like?

May 02, 2026

Seizures can look scary to people watching from the outside.

But for the person having a seizure, the experience is not always what others might expect.

“Not all seizures involve shaking or loss of consciousness,” says Patrick Hartnett, MD, a neurologist with the Ayer Neuroscience Institute Epilepsy Center at Hartford Hospital. “What someone feels during a seizure depends on where in the brain it starts and how it spreads.”

So, what does a seizure actually feel like? Here’s what to know.

What is a seizure?

A seizure happens when there is a sudden burst of abnormal electrical activity in the brain.

That burst can briefly change how you move, feel, think or act.

“A seizure is not one single experience,” says Dr. Hartnett. “More than 2 million Americans will have a seizure, and it can look and feel very different from person to person.”

In other words, there isn’t one exact way people experience seizures. It depends on the type of seizure, where it starts in the brain and whether you remain aware while it’s happening.

1. You may feel a warning sign

Some people have an aura before a seizure.

“Patients often say, ‘I just knew something was about to happen,’” says Dr. Hartnett.

An aura can feel like:

• A rising feeling in the stomach.
• Déjà vu.
• A strange smell or taste.
• Sudden fear or panic.
• Flashing lights or visual changes.

And while people often think of an aura as a warning sign, it is actually part of the seizure itself.

2. You may stay awake, but feel strange

Not every seizure causes someone to lose consciousness.

Some seizures start in one area of the brain and may leave you awake and aware, even though something feels very wrong.

“People may describe tingling, jerking in one arm or leg, a sudden emotional shift, repetitive movements or an out-of-body feeling,” explains Dr. Hartnett. “Others say it feels dreamlike or surreal.”

For some people, it may last only a few seconds. For others, it may be longer or harder to shake off.

3. You may look awake, but not be fully aware

This is where seizures can be especially confusing for everyone involved.

During certain seizures, a person may stare, stop responding or repeat small movements like lip-smacking, swallowing or picking at their clothes.

From the outside, they may look awake. But inside, they may be confused, disconnected or unable to respond.

“Some patients tell us they could hear voices around them but couldn’t respond,” says Dr. Hartnett. “Others remember nothing at all.”

4. You may not remember anything

This is especially common with convulsive seizures, also called tonic-clonic seizures.

These are the seizures many people picture first: the body stiffens, then the arms and legs jerk rhythmically.

“From the outside, these are the seizures people often picture,” says Dr. Hartnett. “But from the inside, most people don’t remember the event itself because awareness shuts down.”

That memory gap can feel unsettling afterward, especially if you wake up surrounded by worried people or emergency responders.

5. The aftermath of a seizure can be intense.

For many people, the seizure itself is only part of the experience.

What comes after can be just as difficult.

This recovery period is called the postictal phase, and it can last anywhere from a few minutes to several hours.

After a seizure, you may have:

• Confusion
• Extreme fatigue
• Headache
• Muscle soreness
• Trouble speaking
• Memory gaps

“Many patients say recovery feels like waking up from anesthesia,” says Dr. Hartnett. “You may feel groggy, disoriented and very tired.”

What should you do if you have a seizure?

Seizures themselves are not usually painful, but you might have sore muscles, bite your tongue, get a headache or get hurt if you fall.

If you have a seizure for the first time, you should always get it checked by a doctor. Emergency care is especially important if a seizure lasts more than five minutes, happens repeatedly without recovery, causes injury or affects breathing.

“Most importantly, we know this can feel scary,” says Dr. Hartnett. “Let’s talk about it together. Getting the right diagnosis is the first step to feeling safe again.”
