Past Lives? (Generational Imprint)

A client asked me:I was wondering if you could possibly help me with this....I've been working on my own psychic pathway now for a while and the subject of past lives have always intrigued me...every since i was a young child I've been haunted by a dream I had of being in a factory and seeing a conveyer belt of severed hands passing by me and what seems to me to be a witch running the machine....The interesting thing is since I was a young child I've had OCD...in particular not wanting to get my hands dirty and always feeling like I need to wash them....is it possible there's a connection here...Any insight would be greatly appreciated....Jason
