I don't wish to be a wet blanket, but I really do not believe you can 'interperet' dreasm at all.
Dreams are the mind's way of collatging the information it's received during the day, and puting into some sort of order - it's a process which no-one really understand, not professors with most of the alphabet after their name, and certainly not people who profess to 'read' your dreams. What is known for certain is that the process of dreaming, whether rememebred or not, is vital for the mind and body's health. You can survive eleven days without food or water, only five days without sleep.
So, depending on who you are, what is important, what stuck in your mind, what didn't, your dream can be utterly different at times during the same night, and certainly on different days as circumstances and thoughts change in a way that is not able to be interpereted in any meaningful way.
The notion of 'reading' dreams is something that give comfort to people who are a little confused and insecure, and looking for meanings to help them reach decisions and move on in their lives.
I would not say you are mad - far from it - but i wouldn't look to any symbokic meanings ion your dreams which are probably not actually there.
