Why did I just start a thread on this? I know this is odd but I need to know if others have experienced this too.

Yesterday my doctor asked me about obsessions. It was difficult to discuss because some of my past obsessions were very odd. She was particularly interested in the sensations and feelings I got from those things. I tried to describe the connection I felt and the pleasure they caused by activating my senses (particularly touch and smell). My senses would overwhelm me to the point of euphoria that felt like an electrical sensation inside my head.

Does anyone know what I am talking about?
