why don't you ask yourself what exactly you are afraid of? A person looking at you? Essentially that is all that it is. Spirits aren't all pretty to look at, and you know, most humans aren't either!
I personally advocate no spirit communication in a bedroom. Most adolescents do this, and that invites not so nice spirits to prey on them as they sleep. It is welcoming a spirit into their sleeping space. No good! Keep it to other rooms in the house, preferably one single room that you can maintain a nice energy in that is clean and welcoming. When you talk to one spirit, it doesn't mean that's the only one around, so as Pyro said, you need to protect yourself. But really, when we say "protect yourself" this doesn't mean that if you don't they will jump out and kill you. That's just silly. Spirits take a long time to do any sort of damage to you unless you ignorantly invite them in some way to have more influencement. If you look at all those horror stories of "based on true stories" it always begins with an invite.
If you use a mirror to communicate, make it just one mirror. Put it in front of you, cleanse the mirror, light a candle, after the goodbyes have been said, cleanse the mirror again and do an action that "closes" the mirror. This could be as simple as drawing an X over it with a protective incense smoke or some blessed water. Really see that that mirror is sealed shut and no longer a window. Then cover the mirror and put it away. In this way, you are showing control and dominance over the situation, and it will not get out of hand. The biggest mistake most people do is give a sense of dominance to the spirit and then they do this to the wrong spirit, and that spirit starts trouble.
