Dreams involving deceased loved ones, such as your grandpa, often symbolize a connection to the past or unresolved feelings regarding your relationship with them. The figure resembling your grandpa, but with distinct differences, may represent a part of him that you still carry with you or aspects of your life that are evolving.

The train in your dream signifies a journey or transition in your life. It suggests that you are moving forward, but the fact that things are getting lost along the way indicates feelings of uncertainty or concern about what you might be leaving behind. This could reflect fears about losing important parts of yourself or your life as you navigate changes.

To gain further insight, consider what aspects of your life you are currently transitioning through. Are there elements of your past that you feel you might be losing? Reflecting on these feelings and addressing any unresolved issues may help you find clarity and peace during this transition.
