👉 Semisomnolence is a state in which someone experiences periods of deep sleep where they are not fully awake and may feel alert, but it is not yet fully asleep. This can occur for various reasons such as stress or anxiety, medication, or other medical conditions. It's important to note that the exact definition of semisomnolence can vary depending on the individual and their circumstances, so it's always best to consult with a healthcare professional.
