Am I Truly Seeing Ghosts Or Is It My Imagination?

I had originally posted my less detailed story on Yahoo! Answers to find answers but nothing was truly helpful. Then I found this website a few days ago and I thought I should try and find answers here.

Starting when I was around eight, I have seen a figures standing by my bed. The first figure I had seen looked like a little boy with bluish tint to him; all I can really remember about him is that he had walked toward me with his hand out and I had been extremely scared.

I haven't seen anything else for a while but, throughout my childhood (I am sixteen now) I would feel something touching me; on the shoulder, the foot, the arm, ect.

The first figure I've seen since I was eight happened this year. For some reason, I've been waking up in the middle of the night around the same time without fail. Normally I fall straight back to sleep but one time when I did wake up, I saw something. It was man who was very tall and so black that I could see his outline in the darkness. I couldn't make out any features except for a fedora hat. The man had been walking toward me with his hand coming up to reach out to me.

Was he offering me his hand? Was he trying to grab me? I don't know but I had become so scared I had jumped out of bed and ran down the hallway. I didn't want to go back to my room but then I thought I was being silly for being scared of something that just couldn't be there. I returned to my room and saw the figure was gone. I decided then I had just been seeing things or dreaming them. I tried to go back to sleep but I couldn't. I don't remember if I had felt threatened by the man in the fedora or not; I only remember being scared.

The next day, the man with the fedora was still on my mind. So I looked him up and saw that people from all over have seen something similar. Websites have said he is a Shadow Man known as the Hat Man. Now, I'm wondering if he is what I saw.

My second encounter happened a few months back. I was trying to sleep and I had woken up to see a tall woman with long hair in a ponytail. She was also holding something in her hand; I want to say it was a staff like thing. She was glowing (I'm not sure if that is the right word to describe her) and she stood out against the darkness. Standing next to the woman was a short man who I can't remember much detail from except that he had a darker feel to him. He didn't glow and he didn't stand out like woman did; I guess you could say he blended in with the darkness. I had been scared but I didn't feel threatened by the woman. I didn't feel safe with the man but I didn't feel threatened by him either. I also didn't jump out of bed like last time; I just shut my eyes and when I opened them again the two figures were gone.

My third and most recent encounter happened just a few weeks ago. I had just laid down ten minutes before when I opened my eyes and saw another man. He had short brown hair and dark brown eyes. He was standing stiffly at the foot of my bed; he wasn't doing anything except for staring down at me. I recall staring at the man for a few seconds then everything is blank from there. My mom told me later that I had come running down the hallway and telling her there was a man standing by my bed. She said I wouldn't go back alone and she had to walk me to my room. When my mom had told me this I was confused because all I remembered about that night was seeing the man staring at me.

I feel like I should include that I've played the Ouija Board a couple of times with my friend. I've talked to some spirits before and all have been friendly except for two or three. The thing is though; I've never played it inside my house; only in the backyard or at a park. I still have the board in my closet; I haven't played it in months. I don't know if the Ouija Board could be causing me to see these things; I've seen figures before I even knew what a Ouija Board was.

My question for you is: Am I just imagining this figures or is what I'm seeing real?
