so you like and prefer angels than demons?
angels are good in nature. so you could talk to them without much worries. if they appear to you in the form of angel.
contacting demons is deadly. i guess you must have some kind of spiritual protection to survive from demons.
but my advice is not to contact demons as much as possible, unless you are a witch, who are friends to demons. you could build a relationship with demons by another witch, if and only if he or she would like to help you.
those are spirits from the west, and many more we don't know. but angels and demons are more significant there. there are also fairies, gremlins, monsters, etc.

cheers,
