Isn't "life" as a mummy extremely boring? So wouldn't a visitor be highly welcome? Say I'm an Egyptian Princess wound up in a body suit so tight it protects me from decay, wouldn't I need a shower, a back rub, a tooth brush, a lung filled with fresh air?
So a visitor would be doomed to unwrap me, do a lot of care, cleaning, spa, hairdresser things plus massages and much beauty work. After that tedious work the bandages have to be washed, bleached, dried, ironed and repaired. Basically the poor souls who disturb me would be immersed with nursing and caring work. Plus much entertainment as I would want to get all the news, gossip, jokes, updates on fashion, how today the mummy style is to wear, could be a long time until the tomb raiders get out again, alooong time!
