I think it could mean they have something for you, spiritually. If they have extended a friendship, take it and see what is behind the curtain. But always tread carefully because the lesson does have the option to be about the messy side of poor human reasoning and the way they treat people.. Always keep yourself a bit guarded until you know their full intent and personality. Always remember, you knew the person... but do you "KNOW" who they have become since then.
