Recently my body started doing this weird thing where it sort of acts out some sort of situation, and I start feeling things that aren't there. My arms and legs start moving on their own, and my breathing gets really fast and raspy. I can usually snap myself out of it, but then it starts coming back again, and I'm pretty scared. I don't know WTF is going on. I feel like I'm acting out some sort of past memory that I completely forgot, but, even when it's happening, I can't figure out where I am or who I'm with, and I don't even know if it's a memory I have or if I'm just going crazy.
