Can Du daydream without realizing Du are daydreaming?

Sometimes I find myself Tagträumen in class without realizing it .... Other times I force myself to daydream in class because the lesson is boring :)

Yes

Of course... then I suddenly realise I'm Tagträumen and get back to what I was doing. I end up in a daydream of this nature pretty much once every five/ten minutes. XP

At least a hundred times a day. :) Mainly in school...
