Lemon in a dream indicates blame. A green lemon is better than a yellow one. A yellow lemon indicates illness and worry.

Lemon indicates illness and worry. Its tree is a man beneficial to people. Eating it indicates gaining money after blame.

Lemon is interpreted as blame. The yellow of it is illness, and the green is good. Whoever sees himself squeezing it will fall into worry.
