well i didnt realise i was in spawn did i

Well spawn is always the area with the cabinets and the auto doors. Unless you were on a weird custom map.

also i got lost and couldnt find my way out - most of the doors wouldnt open and i ended up going round in circles.

Oh, yeah, sometimes the doors are a bit dodgy. You were either in startup time (in which case they go when it finished) or they were bugged. If they're bugged you have to move back from them and try again, or find another door.
