ברכה ושלום!
... במש"כ שבאה האם ע"ה בחלום וכו' - יש לברר אם הייתה הקבורה כדבעי (ולא נותחה אחרי פטירתה וכו'). וכן לבדוק המזוזות בדירתה.

Greetings and blessings!
... Regarding what you wrote that the mother, of blessed memory, appeared in a dream, etc. – it is necessary to verify whether the burial was as it should be (and that she was not autopsied after her passing, etc.). Also, check the mezuzot in her residence.
Summary
The Rebbe writes that when one dreams of a departed parent, it is important to ensure the burial was proper and no autopsy was performed. Additionally, checking the mezuzot in their home is recommended for spiritual protection.
