Happy dream reflecting a could be problem or just paranoia

Yesterday I bought a new computer game. I haven't played a computer game at my house in at least 8 months. It's called Guild Wars. My friends wanted me to buy it so I spent the money i left for myself to go crazy with. I installed it and started playing at 7:00 P.M. I stopped at 1:00 A.M. and listened to music until 4:00 A.M. and went to bed. That is 6 hours at the computer. I didn't even get up from my chair like I normally do when I'm on the computer.

When I went to bed I dreamt about playing the game. After I saw that I had magical powers I knew I was LDing. It's a really fun game so I guess I am not as surprised as I should be, but that may be a warning sign that I could get into the game too much. It may interfere with my schoolwork and that can't happen.

I am in a program that lets you take college classes from Freshman year of High School that gets you your G.E.D and 2 years worth of a university degree for all the colleges in my state. I have to work very hard to maintain the level I normally do. Straight A's. If I failed a class, which I never have, that would mean I would not be able to get that free 2 years of college.

Today, when I went over to my friend's house to help his dad with his yard work since my friend is gone, my friend's dad and I decided to play the game together since he plays it too. we played from 8:00 P.M. to 1:00 A.M. It was a lot of fun. Now I am in the stage where I listen to good music before I meditate to prepare myself for sleep. I don't want anything to keep me from my work at school and yet I want to have fun with my friends and play the game with them throughout the night (Considering I prefer the night). I don't want to try to be uptight about it, but it's just a big concern to me.

The reason that this sparked because I interpreted this dream in two ways. The first way is that I really like the game and I will have fun playing it. The second way is that this game could consume my life. I didn't even sign onto any forums or check daily webcomics for laughs yesterday which is extremely unusual. I just don't play video games that much and I might have gone overboard.

Am I blowing this out of proportion or am I placing correct concerns?

Well, games are fun. Especially when you just start out with one, you can spend quite some hours on it. I think that this isn't a problem yet.
I'm not familiar with the game, but I do advise you not to go in a clan or some sort of official competition. Because if you do that, you can end up rearranging your real life to the game's schedule.(been there, done that)
Something you can do, is just pick an hour or two every day to play. But if something else come's up at that time, just forget about the game.
