I feel a vague sense of unease that some of my ideas are escaping me, or cannot be sufficiently defined. I am often troubled by a feeling of being only half awake, as if I was living in a kind of semidream state which I cannot break out of My ideas become all mixed up, and have no logical sequence or direction. There is a lack of precision or clarity, and exaggeration or distortion of ideas. Sensations are rarelyclear, often bizarre, and tend to be grossly out of proportion. Actions suffer from the same defects.
I think you are saying that the sensations felt somewhat unreal. This is known as derealization. Your thoughts and ideas get mixed up means you may be suffering from some kind of thought disorder. There are two kind of perceptual abnormalities which are commonly seen illusions and hallucinations. Your description fits more into illusions. You did not mention your mood (happy/sad/ anxious) Though you complain about clarity of thought it is not seen in your mail. But information given is inadequate to give a correct diagnosis or advice. Possibility that you are having depersonalization disorder or depressive disorder. But I am not sure because of incomplete information.  You must see a psychiatrist and discuss these symptoms/ complaints.
