Explain what the problem is, and how what you observe differs from what you expect or observe.

As to your question, start by using Serial.println() instead of Serial.print() so that you see each received byte on its own line. Are you sending characters or bytes ?
Running software serial at 38400 is OK for leisurely AT commands but risky in comms mode. You might reduce it to 9600. I assume you have properly set the serial monitor to 38400...
It would be easier to read if you print something between each number, like:
Data = Bluetooth.read();
Serial.print(Data);
Serial.print(", ");
Then you might get
120, 12, 81, 200, 128, 120
Looks like garbage to me. Are you sure your Bluetooth interface is set to 38400 baud?
What app are you using on the phone? Are you sending text?
