From the symptoms you have described, it sounds probably like you are experiencing hallucinations. Hallucination is a perception that it is real although it is created by the mind. There are different types of hallucinations such as:
a) Visual hallucination: where the patient can see things that are not real.
b) Auditory hallucination: where they hear sounds like whistling, music.
c) Olfactory hallucination: sour or foul smelling odor.
d) Gustatory hallucination: perception of unpleasant taste
e) Tactile hallucination.
I would recommend you to meet once with a psychiatrist who can evaluate you and help you with this.
