My dreams have been saying and expressing my fears ?

Sounds like you have a demon to deal with (and I dont mean literally! lol) I mean a problem or guilty conscience to let out? If its a certain fear then you have let that fear consume you so much its stayed in your sub conscience! It's time to face it!! Let it go! Nothing in this world is worth fearing my dear. You have complete control over your mind you can put a stop to it! Once you truly convince yourself your not scared of it (and that doubt in the back of your head is gone) your nightmares will stop. Be strong! Meditate of you need to. Do something calming and think about what your scared of because pushing it in the back of your head so you wont have to face it will make it worse and your guilt will build! So free yourself and face the problem directly. And always think..No big deal!
