We dream in symbols, not literally. If a lesbian to you might be a shorthand symbol to you for the love of women (and I'm not talking male-fantasy girl-girl sex, but the strong, warm love women have and give), or for the strength of women without men, of for women who don't torque themselves around to have to please men, or the love of your girlfriends who care about you, well, you are the one creating the dream symbol.
