hmm.. not uncommon about 4 years having nitemares. but she may be advanced and doing this??
with my son, we got a can of monster spray.. lol.. it was just like glade, and the next one i put a mr yuk on a can of glade.. and voila.. he was a happy camper. 2 is hard to put what is going on in words. you might be in the dream. but she can point to where she is worried. i sprayed the closet and under the bed. i remember when i was little. i dreamt that there were snakes under my bed, so i was afraid to get out and go to the bathroom. well.. for what its worth..
take care
