You wish to redecorate a room in your house. Again your day dream brings needed information. Many people do tend to day dream while driving which I personally believes causes so many accidents. Just watching the road for a long time becomes hypnotic and anyone can 'zone '. This is especially true when people channel through the arts - or do automatic writing or art.
Performers get into somewhat of a day dream like state when they create a role.
The dreams may be physical - or could have to do with opening the heart chakra which is the most powerful 'high' of all. Children day dream for the same reasons adults do. Sometimes children tend to interact in their day dreams often verbalizing at the time. This is often considered fantasy time for the child.
