This suggests that your personal matters are not secure. The tractor trailer symbolizes yourself on your journey through life, together with the sense that you are carrying a heavy "load" or "baggage." Having the door open - assuming it is the door of the trailer - leaves open opportunity for theft or loss. On the other hand, if it is the door to the cab that is open, perhaps you are waiting for a partner or even for a driver, suggesting that you want or need someone else to control your life.

That is the lowest standard size for a swinging door. Patio doors are a couple inches shorter. You can have a door made to fit a shorter opening. It is usually better to raise the header to fit the standard door.
about like 2 meters This previous answer is for a large factory door to allow truck entry. The most common door is the interior household door, which is standardised in Australia where I live . Pre about 1970 the Imperial standard door was 2feet 8 inches. When Metric units were made compulsory in Australia , the common standard for interior household doors was set at 820mm which will now apply forever. The opening for a standard door is about 4mm extra, and the 'Door Stops' which are always 10 or 12mm thick each side, reduces the width of the opening to about 800mm . Therefore the widest item which can pass through a standard door is about 800mm. Also, if the door is attached and will only swing open about 90 degrees, then the thickness of the door reduces the width of any item you ewish to pass through the opening. It is common to remove the door from its hinges to allow use of the full 800mm opening.
