Not exactly. Many spiritual entities are technically extraterrestrial, but it's not like what some imply - aliens from another planet tricking naive humans - but aliens often being spiritual entities, residing far more often in different, often more subtle and 'spiritual' in nature dimensions. Some may also show up on our and material plane of existence as more 'mundane' aliens, but it doesn't mean that's how they are by default. Refer to greys and theories of their bodies (of at least some factions of theirs) being more like disposable flesh suits than bodies they identify with the way humans do with theirs.

Ghosts... probably very rarely. Humans who manage to maintain sentience and some sort of form for longer after death tend to not linger. Most ghosts are pale remnants of who they were, usually lacking any abilities and cognizance to do much for an occultist in a ritual. Far more often it's the other way around - those seeking contact with souls of the departed being scammed by spiritual entities posing as ghosts.
