Dreams about staying in a hotel often reflect feelings of temporary situations or transitions in your life. In your dream, the hotel represents a space of comfort or escape, but the fact that it was actually your relatives' home suggests that you might be feeling constrained or judged by those close to you.

The pettiness about money and food could indicate feelings of discomfort or anxiety regarding resources and support in your waking life. This might reflect a situation where you feel taken advantage of or where relationships are feeling transactional rather than supportive.

Your willingness to sleep on the floor shows adaptability and a desire to maintain harmony in the group, even if it means sacrificing your own comfort. This aspect of your dream may suggest that you are accommodating others' needs, even at your own expense.

Overall, this dream may be prompting you to examine your relationships with those around you, especially in terms of how you share resources and support one another. Consider whether there are areas in your life where you feel undervalued or where you are compromising too much for others. Reflecting on these feelings can help you navigate your relationships more effectively.
