I want to ask you a couple of questions. During my attempts to become lucid in a dream, i have experienced some strange things and I don't know what exactly they are and if they mean that I'm getting closer to LD.

1- During one of my attempts to LD, as I was lying in my bed, focusing my thoughts on having a LD, I suddenly realized that I was standing in the middle of my room, next to my PC. The strange thing is that EVERYTHING looked exactly like i left them before I went to bed, even the PC had the same song opened on Youtube. However, I was 100% sure that I was dreaming, because I didn't remember getting out of bed. So I was trying to make a reality check, but for some reason I could not do it, I was trying to open my eyes even though I could see. Then i got tired of trying to make a RC and went back to bed. In that exact moment, I woke up in the same position I went to bed in the dream.
Question is: was that a dream? Or was it an OBE? It felt really strange and when I woke up the first thing I thought was.... "WTF? What did just happen?"

2- A few days ago, I was trying again to LD, lying in bed focusing my thoughts on this exact intent. Suddenly I woke up (not sure if I was really sleeping though) by a really loud ringing sound, it really pissed me off. Then after 30 seconds I heard it again, even louder and longer. Since it was about 3AM and my roommate was still playing LOL in the living room, having a conference call with other players and yelling them instructions, I thought that my neighbors called the police again. I thought if they ring the bell again, I'm gonna get up and give them a piece of my mind. I'm usually a very peaceful person, but that sound made me SOOOO angry, maybe because I was very relaxed before hearing it.
The next day I asked my roommate why didn't he open the door the 1st time he heard the doorbell ringing. He said what are you talking about, nobody rang the bell yesterday. Then I found out that it was actually a Hypnagogic Hallucination.
Question is: Why did it happen? Is it something that should happen on a regular basis? Is it a good or a bad thing? Is it a sign that I'm getting closer to a LD?

Thank you!
