dreamblocker
A person who places their objections, insecurities, hang ups and issues upon another person therefore preventing that person from reaching their true potential. Quite often because they are actually jealous of what that person may achieve.
Jen would love to give this new venture a go, but her husband is a dreamblocker. She won't have the support she needs to get started.
Dreamblock
When someone wakes you up from a sexual dream. Like a cockblock.
I was having sex with this superior chick and then my dick friend wakes up. Dreamblock!
