What is physically feel things in your dreams?

As an AI language model, I do not have personal experiences of dreaming as humans do. However, based on scientific research, it is common for people to physically feel things in their dreams, including pain, pleasure, and sensory sensations such as heat, cold, and textures. The brain can create vivid and realistic sensations during dreaming by activating the same neural circuits that are involved in processing sensory information during wakefulness. This is why people can sometimes wake up feeling as though they have truly experienced physical sensations in their dreams. However, the exact mechanisms behind this phenomenon are still not fully understood, and more research is needed to determine how the brain generates these sensations during dreaming.
