Crows (and ravens, same family) have been described to me as 'cleaners'. I had a lot hanging around my house while I was trying to sort out my money trouble. Now, my issues are sorted, and there are no ravens. In real life, they clean up things like road-kill and other dead things. It may have been trying to clean up the energy in that area.
Thats so fascinating to me, i've noticed quite a few in my front yard over the past week and sitting on the lounge i find myself just staring at them, DP has been constantly asking me what im looking at!

Sorry for the semi hijack
