Fabric is an interesting dream symbol that can sometimes relate to clothing or to the identity. In this case, the type of fabric can be personifying your character. For example velvet can symbolize wanting to feel special or plastic can symbolize a false sense of identity. If the fabric isn't related to clothing, it can symbolize how you are covering your identity for some reason. If the fabric has a strange power over you, the dream can be exploring the life you are living a lie, or how the sense of 'covering up' is orchestrating your life.
