To dream of your grandmother may represent your intuition or gut instincts in situations that you are already experienced in. Your ability to make a positive decision for the future when you already have previous experience. A situation where experience or already being informed helps you make choices that keep you out of trouble. Feelings that life is unfair because your intuition or luck overpowers your own wishes. Feeling that God or life makes you live in a way you didn't choose.
Alternatively, a grandmother may symbolize intuitive or wiser choices that overrides your decisions. Feeling that life or luck does something for you whether you like it or not. It may also reflect someone more experienced than you having better foresight than you. Possibly a symbol for your marriage, jobs, or family life dictating how your life will be lived. Some area of your life where you are passively decided for. Feelings about family always having to come before your wants. Intuitive choices that is out of necessity or feeling that life only gives you what you need without giving you what you want.
Negatively, a grandmother may also reflect powerful peer pressure that feels impossible to override because you could lose all your friends or an important opportunity. Feeling that you have no choice about where your life is headed as other people seem to be making the big decisions. Guilt or embarrassment for a situation you can't control at all.
Example: A man dreamed of talking to his grandmother about his new child that was almost born. His grandmother looked like she was close to death. In waking life the man was thinking about how his need to have a family was going to kill his sex life. The Grandmother most likely reflected the man's feelings about his wife's pregnancy was permanently overriding his ability to control his sex life.
Example 2: A young girl dreamed of seeing her Grandmother in a shower with her. In waking life she was 17 and taking drugs for the very first time with her friends. The Grandmother in this case may have reflected her feelings about how her social life with her drug taking friends seemed to override her ability to make decisions on drug use for herself because she would lose all her friends if she didn't take drugs by appearing as a sober outsider.
Example 3: A young woman dreamed of sleeping in a bed with her Grandmother and listening to her Grandmother tell her how immoral she was for living in sin with her boyfriend when her aunt told her it was okay. In waking life she felt guilty looking for a new job, but felt she had to. The Grandmother in this case may have reflected her feelings that she was intuitively
lucky to have been given her current job when it was a necessity, while her aunt reflected her alternative intuition making her feel it was important to look for something better.
