To dream of the Amish indicates that your reliance on technology has reached a critical point. Take some time out from the gadgets and screens, making an effort to interact with people and the world around you. Don't be afraid to get your hands dirty.
Alternatively, dreaming you are Amish indicates a preoccupation with personal appearance and superficiality. Try to look beyond this and learn to value yourself and others for what is on the inside rather than the outside.
