Past precognitive memories, or premories, can resurface in three common ways. The first is déjà vu, which is a feeling of familiarity with the present moment. The second is déjà rêvé, which is the memory of a dream connected to the present moment. The third is residual memory, which is the activation of dream content through certain triggers. Studies have shown that déjà rêvé is the most common of these experiences.
Déjà experiences are divided into four categories: normal, precognitive, evoked, and pathological. Normal experiences involve unexplainable feelings of familiarity, while precognitive experiences involve knowledge of future events. Evoked experiences can be replicated through hypnosis, electrical stimulation, or certain drugs. Pathological experiences can be caused by epilepsy, alcohol, emotional stress, certain medication, migraines, tumors, schizophrenia, or dementia.
Sometimes, during déjà vu moments, people may feel things like anxiety, panic attacks, nausea, or even seizures. It’s important to know that in some cases, these symptoms could be related to serious conditions like epilepsy or a brain tumor. If you’ve experienced any of these symptoms or you’re worried about them, it’s a good idea to reach out to a therapist, counselor, or doctor who can help you with your situation.
