I'm a female. It was more of a reality that I was treated mean when I was younger (or even now by my sister). I don't know what to do about my sister's behavior since she doesn't care to change. I've been too tolerant when I was younger, but I'm not as patient as I used to be. I'm tired of mean peopel and I'll tell them to go away now except I'm stuck with my sister for life.
Did my additional feedback help you to derive more from the dream? You wrote that you sensed more than you have provided in your analysis. I don't know if my feedback relates to what you sensed or if it's something more. If someone says something to you in a dream (any dream or not just this dream), could it ever mean what the person really thinks of you?
The childhood experiences with your sister have followed you into adulthood. That is reflected in my analysis.
--childhood best friend-reconnecting with undeveloped positive aspects
-I grew up with-following you into maturity/adulthood
But what other issues have followed you in adulthood? Are there any issues that you have kept private? The bedroom part may be speculating on the 'hidden' aspects related to sister or other issues not related to anything intimate. If there are issues of intimacy or sexual experiences then that needs to be looked at.
As for what someone says in a dream meaning it is what they think of you. It likely is saying something of what you think of yourself although it could be what they think. Your dreams are about you and depending on who says what and in what context what is said is something you saying to and about yourself. Or it could be what you perceive another person thinks about you.
Look at your early life and determine if there are other issues the dream could be addressing, other than the sister relationship.
