It is possible that what you experienced as a boy could have been a hallucination, especially considering that your parents were indifferent to it. Hallucinations are perceptual experiences that occur in the absence of external stimuli. They can involve any of the senses, including hearing, seeing, feeling, smelling, or tasting something that is not present.
Hallucinations can be caused by various factors, including stress, sleep deprivation, certain medical conditions, and even some medications. In children, hallucinations can be associated with fever, illness, or even vivid imagination.
However, it's also worth noting that children's brains are still developing, and they might have more active imaginations than adults. Sometimes, they might misinterpret normal sounds or movements as something else, leading to experiences that may seem like hallucinations but are, in fact, a product of their vivid imagination.
If this was an isolated incident that didn't cause any distress or impairment, it may not be a significant cause for concern. However, if you have been experiencing similar phenomena recently or if it's causing distress in your life, it's essential to discuss your experiences with a healthcare professional, such as a psychiatrist or psychologist, who can help assess and understand what might be happening. They can determine whether it's related to any medical or psychological condition and recommend appropriate interventions if necessary. Always remember that seeking professional advice is the best course of action when dealing with unusual or distressing experiences.
