I often hear of people saying they wake up in the middle of the night, terrified. Overwhelmed with negative energy, and they can't move or scream. Sometimes they may see a figure, or feel like someone is sitting on them. You know what this is? Sleep paralysis. During REM sleep, our brain shuts off movement to our body so we don't "act out" our dreams in real life. Sometimes, we may wake up during this stage, and our body doesn't immediately restore movement, causing us to feel paralyzed. Our brain is also still partially dreaming, causing strange visions and feelings. Now you know. Sleep paralysis stories, share them in this thread.
