Why should you not wake a sleepwalker?

It is generally advised not to wake a sleepwalker because it can disorient and confuse them, potentially leading to accidents or injury. When someone is sleepwalking, their brain is in a state of partial wakefulness and partial sleep, and waking them up abruptly can disrupt this state and cause them to become disoriented or frightened. Additionally, sleepwalkers may not be fully aware of their surroundings and could potentially injure themselves or others if they are suddenly awakened.

Instead of waking a sleepwalker, it is generally recommended to gently guide them back to bed or to a safe location, while avoiding any sudden movements or loud noises. It is also important to make sure the environment is safe, removing any obstacles or potential hazards that the sleepwalker could encounter. If the sleepwalking persists or becomes frequent, it is advisable to consult a medical professional to determine the underlying cause and receive appropriate guidance and treatment.
