According to numerology, it is not a good sign to wake up in the middle of the night and see that your door is the tomb door. According to the principle of geomantic omen, doors, as entrances and exits of houses, are related to the fortune of families and the well-being of residents. Mausoleum door usually refers to the door related to the cemetery. The gas field of mausoleum door is cold and gloomy, which will bring negative energy and adverse effects to people. Seeing that the door of one's home is the tomb door may mean the decline of family wealth, poor health, interpersonal problems and so on.
But when answering this question, I can't make an accurate judgment only by relying on this description. The specific impact of the tomb door needs to consider other factors, such as the specific location of the door, the surrounding environment, the date of birth of family members and so on.
If you are very concerned about this matter, I suggest you consult a professional feng shui master or numerologist, who will give corresponding answers and suggestions according to the specific situation.
