Nightmare?

If I were to go lay down and begin to sleep, would i dream? If so what would it be? How do i know as of right now I'm not dreaming? In some way i could be dead right now, and this is my time for sleeping forever. Would it all be fake? Or is being awake the fake world, and through our dreams we see the real? Are they both real...are they both fake? What about the pain, sorrow, joy, anger, happiness, despair...the love, is that all real, or fake? All that I've seen through these two round spheres built and constructed for sight, or are they just part of a dream? Or could it be someone Else's dream...or nightmare? Please someone tell me I'm not a nightmare, please someone. I don't want to cause pain to someone, anyone even if i am part of another world in there mind. Someone, anyone, anything please tell me I'm not, that I'm not some nightmare to haunt children, to frighten those in pain. Tell me, please, i want to be...i want to be someone to feel feelings...to love those who i care for. Tell me that I'm real, that I'm tangible, and not alone, and in waking sight of some heart broken soul, torn apart by someone or something they loved with all there heart. I want to be able to love...
