My dreams are always sinful?

I'm a born again Christian, at least I try to be faithful but I having a hard time in my walk lately. My dreams are plagued with sin and uality, some of it is strange and off-the-wall, other dreams are disturbing. Why are these dreams happening so often and how can I get them to stop? Can I be judged for my dreams? Long before I became a Christian I had a dream in which the Lord spoke to me and told me to "Come to the Cross", I never forgot it, now 26 years later I have decided to listen to that dream, but it hasn't been an easy road for me. I find it hard to pray, to meditate on the Lord, to read the Word, to be obedient. All these things I'm struggling with. Now my dreams are full of sin- adultery, acts, drug use, alcohol abuse, , etc. It is disturbing to say the least. Also a couple of years ago I had a dream that i was at an , and there were bodies having all around me. I knew that I was saved and I didn't want to be there so I was looking for a way out. Then I went down a dark corridor into a dark room where a fat man was sitting in a chair with a ratty white wifebeater shirt with stains on it.. He looked at me and sneered then he got up from his chair and pinned himself on top of me and he spit in my face. I woke up feeling very disturbed and even violated. What is going on with me?
