I was in the hospital, visiting a friend, but I don't know him in the real life. In my dream, I didn't know the reason why this person was in the hospital. We were chatting and laughing, he looked fine, until he put his thumb up - I saw that this finger was missing, therefore this was the reason why he was in the hospital.
Dreams involving hospitals often relate to themes of healing, support, and care, suggesting that you may be processing feelings about your own health or the well-being of others in your life. In this case, your dream features an unknown friend, which could represent aspects of yourself or your subconscious that you're unfamiliar with.
The hospital setting could indicate a place of healing, and your positive interaction with this person—chatting and laughing—can signify a desire for connection or support, especially during challenging times. The missing thumb may symbolize a perceived loss or a sense of vulnerability, possibly relating to aspects of your life where you feel incomplete or struggling.
Overall, this dream might reflect your concerns about someone in your life or your own feelings of inadequacy. It may be urging you to look deeper into your emotions, your connections with others, or areas in your life that require healing or understanding. Since the friend in the dream is unknown, it could also indicate a need to embrace the unfamiliar or acknowledge parts of yourself that you are not fully aware of.
