A bed is a place where you go to relax and to sleep after a long, hard day, so a bed in a dream symbolizes rest and relaxation. If you dream that you are in a bed, it can be a sign that you have been working too hard and you need to relax.
If you dream of a newly made bed, the dream could be telling you that you need to approach a problem in a new way.
A dream that you are huddled underneath the covers in bed is a sign that you are feeling vulnerable and are looking for safety and security. This dream may represent a metaphorical desire to return to the womb.
A dream that you are in bed with someone else can have sexual connotations. However, this dream can also mean that you wish to share something with that person, or that you admire some of their qualities and would like to have these qualities yourself. If the person you are in bed with is somebody that you do not like in waking life, you may be worried that you are becoming like them in some way.
