DREAM DICTIONARY - Outer-space :Space can symbolise several things that we associate with it. Space is literally out of this world and links to something we cannot imagine(E.g. "I cannot ever imagine being homeless"). It is also endless and so can link to a feeling like that such as "there is no limits to my anger".

This website has a huge collection of dreams. The accuracy of the dream symbolism depends on a huge huge number of practical examples. If you have a dream which you feel you understand then please send it to me at firstname.lastname@example.org and I would be delighted to add it to the collection.
