Am I seeing ghosts or am I crazy

I've been seeing these things for about two-three days now (I'm not on any medications). The first thing I saw was the day after me and my boyfriend broke up. I was playing my PS3 and he was laying on my arm. I could feel his heat and hear his voice and I felt his breathe on my arm. I got up to change clothes and was talking to him in the mirror, but when I turned around... he was gone. Later that day he was over my shoulder asking me why I was crying (I was crying because I thought I was crazy). The next time I saw something was when my friend was spending the night and I looked in the mirror and saw a hand coming out of my closet and blood filling my room. She was on the phone and I didn't want to scare her with it. I just tried to ignore it. Then tonight I saw a man... he was demonic and was standing in one of my corners behind my friend. He was an orange color and had spikes all over his back. He just showed up and had horns on his head and two sets of eyes. He just watched her... I got worried and asked her to sit next to me. Then he started watching me. I talked to her about him and she asked me to draw a sketch... so I did. We were scared... he eventually went away. I later got up and got a drink, when I came back she told me this, "there was a hand coming from behind your tv stand. it looked like a young childs hand and it was very pale like an anemic child. then the hand slowly pulled away and you walked in. i never saw the body though" I later saw the same orange man following me. I'm now keeping a sketch diary of what I see and at what time. I'm really freaked... I'm not sure if I need medication, or if what I'm dealing with is ghosts.... please help.... and hurry.

The first thing the boyfriend image, is Dante' he is the demon and a shift changer. The second one is an alien that has come to size you up for sale. The hand in the closet with the blood is the blood of Jesus. You are about to be taken out of reality. Unless you change the way that you think now, it could happen at anytime.
