Lyric discussion by Bobo192 

There are two schools of thought on this song, one of which, like so many others (if you view my most recent comments, you'll see what I mean) is that this song is indeed about drugs. The door is, without doubt, the barrier that separates you from another person, be it spiritually, rather literally, or in a drug-based way.

I'll say a bit more about this song later today, if I get lucky... bicycle.
