Encounter With A Spirit

I've recently come to terms with the fact that I have some sort of abilities. I'm just starting to research about meditating, living a healthier and more positive lifestyle and becoming closer with God and putting my trust and faith in him. I feel like I need to do that first before I start to learn more about my abilities... But I still have some experiences from time to time. You can read about them in the only other post I have so far, dated 2/5/2014.

I felt the need to hurry up and post this while it was fresh in my mind. I seem to come into contact with spirits (I think) just before I fall asleep. I hear voices and sometimes see people. In the past, it sounded like a static TV with the volume up loud and its hard to decipher what they're saying. Last night my toddler woke up in the middle of the night. After I put him back to bed, I went to lay back down around 5AM and was just about to falling asleep. I saw a tall, skinny man with a long gray trench coat, and long thick dark hair. He was with a woman, but I could only see her face. I felt like I was in a room with them and they were there to see me, as if for an appointment. They both looked at me and the woman said "I don't think she's ready, we should go somewhere else". Then the man opened a door and they were about to walk out. On the other side of the door, it was pitch black. I said to them "please wait, I've never done this before. Just give me a moment to calm down and get ready". Then all of a sudden, my whole body started to vibrate. It felt like an electric shock, like I had just put my finger in a socket. I could physically feel my eyelids fluttering. I got so scared that I forced myself to wake up and I woke up with a huge jolt. I was wide awake after that and nervous to go back to bed...

THAT has never happened before. I have heard things and sometimes felt people talking in my ear, but I have never felt that sensation through my whole body. It only lasted a few seconds...

Does anybody know what happened to me? My first thought is that the spirit maybe tried to enter me? That scares me a bit. I am constantly praying to help keep me calm during those experiences and keep anything negative away from me, my family and my home. I'd rather just communicate with them by talking with them, I don't know about allowing something to enter my body. Or was that my body prepping to do something else? I have no clue...
