Dream about someone hiding under a blanket is a premonition for your tenacity and refusal to give up. You are trying to avoid an issue, responsibility or situation that is causing you emotional pain. You are experiencing cold, hard times. The dream indicates unfinished issues that you need to tend to and perhaps even repair. You are feeling burdened by the responsibility of taking care of someone else.
Someone hiding under a blanket dream is a symbol for death and the darker aspects of your character. You may feel someone else is running your life or dictating what you can and can not do. You need to relinquish your worries and let go of your old problems. It is a warning signal for your lack of self confidence or conviction in the pursuit of some endeavor. You are dwelling on the past too much.
If you dreamt about someone hiding under a blanket:
You generally seem very matter-of-fact about a lot of things, including romance. You base your feelings on how well a certain person looks and dresses, or how efficient, neat, and tidy they are. However, today may bring with it some really earthy fantasies – like the thought of wrestling in a slimy mud pool, or passionately embracing amidst the leaves and earth on a forest floor.
