Can the messages we receive be false?

Hey, I've never been good at channeling or automated writing... I mean, sometimes it happens and everything is fine, but I have trouble with some of them.. I got one that was in latin or something.. It looked like latin but when I tried the online translators it gave me some thing I don't think it meant at all.. A friend of mine wrote something down that made me question.. The lady spoke through her but was talking to me. She said I needed to find my spirit guide. I've thought and thought on it, but I still don't know what this guide is. She said it was an animal and has presented itself to me before. I know this might be better in the guide section but really my question is, could she be sending me on a wild goose chase? I mean, i don't think my friend confused the writing with her own mind, the lady talking knew too much about me. So... can they lie? Like confuse us? I don't see why they would but this was a year ago and I STILL can't figure it out. Help?
