To speak with an accent in your dream suggests that you are having difficulties conveying your thoughts. Consider how you feel about the accent. If you feel the accent makes you stand out in a negative way, then it signifies feelings of insecurities. If the accent makes you stand out in a positive way, then it symbolises an air of confidence.
To hear someone speaking with an accent in your dream represents something familiar yet different. You are getting the gist of a message, but you still do not completely understand all of it.
