Are you the type of daydreamer that needs to be sober, relaxed, and free from any angst in order to MD? Or are you able to MD even if you have taken drugs or alcohol, are in a bad mood, feeling anxious or upset? - basically anything that has your mind stimulated?
I have found that during the times that I really could enjoy the escape, my mood has often times prevented me from enjoying a much-needed daydream. If something has happened to me that has upset me, forget it. If I have had too much alcohol, same thing. It's as if I need peace in order to do it, even though during the most difficult times when I might require some escapism -- not being in the mindset prevents me from escaping.
Does this sound like you? Or can you MD through your moods or substance use?
