Energy Or Child's Spirit?

Whenever I go to bed at night, I feel and can see the energy of what looks like a person (maybe a child?) standing in my room. I'm not sure why it is there, but it is always in the same place as other nights when my lights are turned off. I am a little frightened of it, so I always cover my head when I go to sleep. I do not feel the energy/child to be bad or harmful to me. After I posted my other story, I realized that the energy/child in my room might be the girls voice that said "Gwen, Gwen come out and play". I'm not entirely sure if this is correct or not. What do any of you think about my energy/child? If it is a child's spirit, should I try and communicate with it? I have a pendulum (don't worry, I know how to cleanse it and not ask not needed answers), Should I try communicating with that?

Also, how do you get in contact with your spirit guide? Does meditation help you with developing your psychic abilities? I've been trying to meditate for a couple days now and nothing has happened yet. I feel a little angry that it hasn't been helping my abilities yet (If you could help me with how to correctly meditate, that would help). Oh, I really would love it if you could help me with all my questions. I would be very grateful. ^_^ Thank you!
