Dreams about being in a hostel or hotel often symbolize a transitional phase in your life or a quest for comfort and security. In your dream, the focus on getting your children settled suggests that you may be feeling a sense of responsibility or concern for their well-being, which is reflected in your worry about the open window and your son's safety. This could indicate that you are navigating some uncertainties in your waking life, particularly related to your family.

The presence of Gronkowski, a well-known football player, may represent strength, admiration, or a desire for validation. His interest in you could symbolize a longing for affection or recognition in your personal life. The feelings of jealousy when you saw him with another girl might reflect your insecurities or fears of not being enough in relationships.

Ultimately, this dream could be highlighting your protective instincts as a parent while also exploring your desires for personal connection and affirmation. Consider how these themes relate to your current life situations, and think about how you can balance your responsibilities with nurturing your own needs and desires.
