I feel the exact same with DoTA 2. Makes me relaxed and helps me sleep. Especially the part with "replaying some of the moments from the video game in my daydreaming imagination". Resonates a lot.
You must be getting much less frustrating team mates than me haha :)
Every time I hit the Play button for ranked I feel such anxiety with Dota2. Normally I just play in the arcade, like 12v12 or some tower defense instead.
