Impending Sense of Doom

Somebody please help me... For the past few weeks I have been feeling this bad premonition that something bad is about to happen. Either to me or someone close to me.
I really do not like this feeling. This negative energy that I feel looming in the future makes me sick to my stomach... :( I have been having vivid and weird dreams lately, which is almost a sure sign that something not to my liking will happen soon. Help. :(
