I think you are saying that the sensations felt somewhat unreal. This is known as de-realization. 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 de-personalisation disorder or depressive disorder. But I am not sure because of incomplete information. You must see a psychiatrist
and discuss these symptoms/ complaints.
