No, you will not die in reality if you die in your dreams. Dreams are a natural and common occurrence during sleep and are a result of various brain activities. When you dream of dying or experiencing any other extreme events in your dream, it is simply a product of your subconscious mind and imagination.
Dreams can be vivid and emotionally intense, but they are distinct from reality. The feelings and sensations you experience in dreams are not physically real. When you wake up from a dream, you return to your waking state, and your physical body remains unharmed.
The idea that you can die in real life if you die in your dreams is a myth and not supported by any scientific evidence. Rest assured that dreams, no matter how intense or unsettling they may be, cannot cause harm to your physical body. They are a natural and essential part of the sleep cycle and play a role in processing emotions, memories, and thoughts.
