What Are Dreams About

The other night I had this dream,that makes no sense. I write them down as I go and with manifesting and go to sleep in my wish fulfilled this is what I have come to interpret of the latest "weird" one.  There was a spider on the floor in the living room, and I was screaming. My dad was there to kill it. My mom was telling me to calm down so I was yelling at her. My dad told her to let me yell, let me get through it, Next thing I know I'm feeling these pains at the base of my head under my hair. I pull my hair up and feel and I feel these round things biting at my head. I grab them and pull hard ripping them out and throwing them on the ground. There are 3 of them. Black little round things with teeth. Basically it ended. What did I take from this? Well when you go to sleep with stress on your mind, that is what you can expect to keep having happen. I have been really focusing on going to sleep with a smile, with the end result. What am I working towards and dreaming of it already being here. I am constantly working towards shifting my reality, and it all starts when you go to sleep. Now this wasn't a lucid dream. I have had plenty of those, and Ill get into those later. This was my subconscious telling me to stop letting stress grab a hold of me. My dad was always the one who let me scream, Whenever I see him in a dream, knowing that he has passed away. I am able to pull myself out of it and watch from  the outside. Hard to explain, but when you excercise your brain, you can consciously change things, even in a dream. The round balls with teeth, trying to take control of me and shift my mind. I took control and ripped them out, I took my power back. When it comes to manifesting, the first thing you need to realize is you cant WANT it. You need to focus on already having it. I watch Elmer O Locker Jr. on YouTube. and the teachings I am getting there have been monumental for me. I'm going to get more into dreams, especially the lucid ones next. stay tuned.
