Why do vampires sleep in coffins?

Vampires do not exist they're only in movies to make it scarier. The first reference to a vampire sleeping in a coffin was in the 1931 movie Dracula. The first reference to vampires sleeping in anything other than a bad was in Bram Stoker's novel Dracula.

A few of the more famous vampires were shown sleeping in their coffins which has given rise to the stereotype. This is simply because that was where they found themselves when they woke up and it is comfortable and convenient and they certainly paid enough for it, so why not continue sleeping there? Some have a great sense of tradition and family pride and that it as proper for them to continue with the heirloom. In fact, a vampire has no real need to sleep in his (or her) coffin.

Alternate Viewpoint:

I believe vampires do exist. They're not like the ones that you see in the movies though. These people actually choose to drink blood as a preference and live the lifestyle based on what they've seen in movies.
