If you felt the sensation of a lizard crawling on your arm, but there was nothing there, it could potentially be classified as a tactile hallucination. Tactile hallucinations involve perceiving sensations on the skin, such as crawling, itching, burning, or tingling, without any external stimuli causing those sensations.
Tactile hallucinations can occur for various reasons, including stress, anxiety, sleep disturbances, medication side effects, substance use, or certain medical conditions. Sometimes, they can be related to sensory processing issues or neurological conditions.
If you are experiencing tactile hallucinations or any other unusual sensations, it's crucial to talk to a healthcare professional. They can conduct a thorough evaluation, consider your medical history, and provide appropriate guidance. They may want to rule out any underlying medical conditions or discuss factors that could be contributing to these experiences.
Please reach out to a parent or guardian, or another trusted adult, and share your concerns so that they can help you seek the appropriate professional help. It's essential to get a proper assessment and address any potential issues to ensure your well-being.
