I am a computer science major and I have a problem for past 10 years or so. Its only now that I realized that how badly it is effecting my personnel growth an everyday activities. Sometime it makes me really depressed and inferior (all the time) because of the fact that I know I am not growing because of this problem. I am a fulltime employee and I still observe that problem.
Any help for me will go a long way and if I could solve a problem I would try to reciprocate to this forum in whatever way I can. The problem is:
Whenever I am about to concentrate on anything ( regarding my work, planning of future) I get distracted and see images of the past places that I have visited in my life. I start thinking about the problem at hand and as and when I am thinking suddenly “out-of-the-blue” I see an image of the a place that I have visited in the past. Now what happens is that In future if somebody ask me to think about the “same” problem and when I recall….i see the same image that I had seen when I first started thinking about the problem.

I want to know is this normal? If it is then how do people study because it’s a serious distraction. Until 2002 I had never seen that problem ( I was in second year in my degree course then ).
