Wow! As much as I have lifted in my life I can't say I ever remember dreaming about weight.
Maybe its true that dreams are our mind's way of working through things. If dropping weights on yourself worries you, try to face this fear. You mentioned in a seperate post about lifting in a cage and the security you felt there. Working on form and safety features like clips and clamps on your barbells may also help you feel more secure.
Not saying you have any issues with the weights, I just wondered because you mentioned these things and they seemed related. Take care.
