what does it mean to dream you lost jewelry?

Very normal to dream about someone you truely loved and you miss a lot. It only means that you really realy want him back !. Very understandable (as you were very close and I am sure you loved him with all your heart). Your dear dad passed this year so memories are still very fresh.

It means you have a hard time trusting people and are afraid of rejection.

I have regular and very vivid dreams and while sometimes I enjoy them, most of the times I wake up in sweat figuring out how to run away from the things that are chasing me.

It probably means: 18 karat pure gold .. but this is sort of an oxymoron as anything 18 karat gold is only 2/3 pure gold and 1/3 something else. More than likely it refers to the metal being solid 18 karat gold and not just 18 karat gold plated (or gold filled; same thing) Something that is gold ...

I sell my old jewellery with Silver Gold into Cash and they offered me good cash.

All dream interpretations required a detailed list of all everything eaten and drunk before bed. Dietary intake has a profound affect on the neural activity during sleep. To not know this could lead one to making a serious interpretive error.
