I get obsessed with df about twice a year for a month or so, my obsessions change often. Right now i'm obsessed with tolkien. In a month i'll probably be obsessed with space, so on so fourth.
But when i am obsessed, im really obsessed and spend every free moment (eg when i'm not working) doing something related to it at the expense of all other things. In dfs case that can mean, browsing the wiki, relistening to all the df talks, playing df etc. Im sure i've listened through the df talks completely about 10 times. It's probably unhealthy.
Sounds sort of like me, I will forget about DF for a few months then remember, comeback and spend a few days to a couple of weeks doing almost nothing but DF in my free time.
When I'm on a DF bender I spend my time tuning the raws, generating dozens of worlds ,checking legends again and again until I find the perfect world with the help of perfect world and legends viewer and only then I'll play, but tend to end up getting disillusioned because I'll want whatever feature was just mentioned in the latest dev log and stop playing rather then let it sour my overall DF experience.
My favourite time to play DF is during release phase with the bug fixes and little features work because every new dev log just hypes me more, that is when I get get really obsessed and take my laptop with DF on it to family functions and a portable hard drive into work, now that it is unhealthy, it just that it happens that this time my usual obsessive DF swing aligned with a release closely enough that I'm stuck playing lots of 44.12 while jonesing for the next feature hit.
Once I stayed up all night watching a goblin siege massacre my fortress in Meph tileset. "Who dismantled the cage traps?" I thought. Then I woke up, realized I was dreaming, ate breakfast in the real world and went downstairs. My sister was staring at the Your defenses have been overcome screen. Turns out she snuck downstairs AND DISMANTLED THE TRAPS FOR RESOURCES! A lot of screaming and #!!?$%&$#%@]#?"#$@\%&&%# ensued. That's the story of how I dreamed I lost a fortress, at the same time my sister had destroyed my fortress in the exact same way.
So you share a fortress with your sister? is it like a hot seat communal game? could never bring myself to play a communal game, I'm too much of a control freak to allow someone else to touch my fortress.
Two days ago I actually woke up and thought I was dreaming. I was actually looking at my bedroom, but in Meph tileset. I went down the staircase and everything returned to normal.
I can't tell the difference between real life and DF half the time now. I probably should see a psychatrist. My other personalities have gone away now, though.
You might want to get that assessed if possible, I had a friend who's brother had to be committed because he truly believed he was Jesus, was bought on by a meth addiction if I remember correctly, better safe then sorry.
