Yehhh had this before. One time I was in the field next to my house and the cows in there escaped and I was like "I better get them back", "But it's just a dream! Ah well better get them back anyway just in case!".
I feel weird leaving things that would need attention in real life, I've had the night time thing as well like you, not wanting to make a sound in case I woke someone up, or getting embarassed about doing something when my parents are there. I think in time we'll get over it though!
