Just a simple question for those that have a gift of being able to share dreams or have telepathy skills.

Is it rude to just drop in on someone without their prior knowledge? I have felt it a few times lately and then I have to block it out. On the other hand, I find myself wandering where I have not been invited and not knowing for sure if it's imagination or real, I still feel like I may be intruding.

No skeptics please. If there is a standard protocol to this please post.
