I have always wondered why we dream what we dream. Usually if you think back you were thinking about something that then caused you to dream that. You subconscious mind does that I guess. Like for instance about my surgery on my ear. I have ringing in my ear for over 20 years now (tinnitus) It was brought on by getting a cold. Doc said the cold virus attacked my nerve in my ear and killed it. I have never heard of this. But if you get   antibiotics  within 24 hours it will not effect the ear nerves. When it first started I could not even listen to the car radio. It sounded like I had broken speakers. So I had to listen to talk radio which wasn't so bad as far as the sound goes. It took 3 courses of antibiotics to get my hearing back to where I could listen to music without the distortion. As of right now I would say I have about 10% of my hearing left in my left ear with the constant ringing day and night. 

As of 2 days ago I just started a new medicine from online the guarantees it will stop the ringing. I will give the meds 30 days and see. 2 capsules (horse pills) a day in the morning. lol
