This dream may symbolize feelings of betrayal and distrust in your waking life. The room with one doorway and one window represents a confined and limited space, possibly reflecting a sense of being trapped or restricted in a situation. The old woman collecting her things may represent a part of yourself that is trying to move on or let go of something. You, as the dreamer, are protecting her, which could suggest a desire to protect this part of yourself. The knife in your hand may symbolize your readiness to defend and protect yourself. The Russian men in the room may represent opposing forces or conflicting aspects of your personality. The fact that you are watching them and are distrustful of each other suggests a lack of harmony and unity within yourself. The second Russian man entering the room may symbolize a new challenge or threat to your sense of security. The dream takes a dark turn when you end up between the two men and they stab you in the heart. This could represent a fear of being caught in the middle of a conflict or being hurt by those you trust. It may also suggest a fear of being vulnerable and exposed. Overall, this dream may be a reflection of your inner struggles with trust and betrayal, and a reminder to be cautious and protect yourself in your waking life.
