Hmmm, since you already have developed a true belief system, maybe I (schizo, dunno if you are) can help...
The battles seems to be between me, god, and satan. During the day, Im completely normal. But, it's at night when the thoughts happen. I think Im being attacked by demons, aliens, or monsters. It's completely weird. Sometimes, I cant even sleep at all. Sometimes ill have my eyes closed for a bit and the thoughts just bombard me and when I open my eyes and look behind me, I think somethings gonna come attack me. And also, dont let there be a show on tv about God, or an advertisement about a scary movie, it just seems like its too good to be true. What can I be experiencing?
You truly believe and know there is a God, you may be able to catch glances of what is happening in the spiritual world, but you will not be able to understand it completely...we we're not created that way. Your faith (which will be with you 20 years from now, solid as a stone) is causing you to feel your heart, then insecurity comes in and screws it all up...it will happen all the time and I suggest you don't fight it...be submissive and let it happen, it sounds like the end result is a negative, but I assure you it's not, it's very...hmmm.....peaceful really...
You are in this somewhat deep...that is why I am offering this off-the-wall advice to you. Others reading this post, I am aware of the odd nature of my suggestions...I had to go through this crap all alone and it sucked, I do think it is somewhat helpful and you are more than entitled to think differently (duh)...
