OMG! Was I too tired? Or it really happened?

Something strange (or may be..spooky?!) happened to me yesterday...
In the afternoon at about 4 - 5pm, I was lying on the sofa comfortably in the living room watching TV. It's too comfortable until I fell asleep. I was totally unconscious until the moment that I felt something..a voice.. an unclear voice..blurrish voice just in front me.. to be exact -- just in front of my face..it sounded like a male voice..talking. I really couldn't hear properly. I was still lying on the sofa but my body couldn't move at all. My eyes couldn't open neither. But my mind was halfly conscious at that moment. I forced myself to move and to open my eyes. But I just couldn't do that! OMG..what was happening..Luckily after a while with my strong attempt, I suddenly became fully conscious and my body was fully released. My eyes opened. And I noticed that no body was actually around me. No voice. No man. Nobody.. except the TV which was still showing the program that I was watching before I fell asleep. I was so shocked of what had happended...It did not end..
Late at night I slept at about 12+. Strange thing happened again. I was lying on my left side on the bed with my back facing the wall. I couldn't move again! But my mind is awake..at least 70%. I felt something...somebody..climbing up to my bed..to my back..between me and the wall.. Oh f**k! What the h*ll is happening??! I started to pray..ptay and pray..so hard. Finally after a few seconds my body was be able to move. I turned my head around, my heart beating was so fast, and nothing..nobody behind me on my bed..nobody in my room. I quickly switched on the light. Damn! What had happened to me??! When I looked at the clock, it was about 2+. I didn't really care and I was not really very scared. I continued to sleep with the light on.
Two strange incidents in a day, god knows what happened.
