Possible Abduction? Please help me.

If anybody can contact me I would greatly appreciate anything. I'm not crazy. I'm a smart, stable person who prides myself in my rationality. Last night (December 26, 2009) me and two friends went outside to our friends car to have a cigarette. We arrived at the car around 1:42 AM, and perhaps two minutes after that there was a very bright flash of light, followed by a second flash about 7-10 seconds after. It was raining lightly (we were sitting in the car the entire time) so we dismissed the flashes as lightning but we heard no clash of thunder. We discussed the flashes briefly, but did not dwell on the subject as it seemed unimportant at the time. While we are having our cigarettes, my friend and I begin a conversation. My friend had his ipod on and played some songs for me. After listening to about 3 songs and talking for about 4 minutes, I realized that my friend and I were having a conversation we had about 3 weeks ago, VERBATIM. He was listening to the same music, making the same comments about the songs and singing some of the lyrics at the same specific times. I responded to a few of his questions in an indentical manner to how I did a few weeks before. I realized this but didn't think it to be significant as these things do happen sometimes. My estimate is that the conversation went on for about 4 minutes before I realized that it was an exact repetition of previous events. I have had deja vu before many times but this was a powerful realization that I was repeating a conversation almost unconsciencely. It was like witnessing a glitch in the Matrix, if that can put it in perspective to somebody. It was late and I began to fall asleep in the car, with my elbow resting on my knee and my head resting on my hand. I began to fall into a state of 25% consciencness 75% sleep. I remained in this state, mostly asleep, letting my mind wander. I thought how strange it was how tired I was, how unusual the conversation was I had with my friend, and the two flashes of light we witnessed. It hit me immedietly what had happened to me. I sat up and exclaimed "We were abducted by aliens." My friend said "What....did you just say we were abducted by aliens?" He began to panic a little (he has some anxiety issues so a panic was not unsurprising) but I was able to calm him down and contain myself. I took out my phone and wrote a draft text message (really a note to myself) that read "I was abducted by an alien." I remained calm while I was writing this on my phone but my heart was racing, I felt light headed and my vision was blurry. The sensation was similar to that of a panic attack. My clothes did not appear to be dishoveled or changed. I then realized (after handling my cell phone) that my middle, pointer, and thumb fingers on my left hand (the hand I had been resting on) were coated in a fluid. While it's difficult to say it had a consistency similar to that of semen. This was highly unusual so I went back into the house and wiped my hand on a paper towel, folded it, and put it in my pocket. I still have the paper towel and if I feel compelled to do so I will get it examined. I spoke to my friend and assured him that it didn't happen. I believe he may think it happened but the simple truth is that It would freak him out too much. We went back indoors at around 2:20 AM. This means that we spend approximatly 40 minutes sitting in my friends parked car. While we were in the car for some time, perhaps as much as 1/2 hour, I don't believe that we spent 40 minutes in the car. At this point in time I find whether or not I was abducted very difficult to say and I am weighing all evidence I have before I could make the claim that I was. Jumping to conclusions will not help anybody. Acknowledging the minute possibility that something could have happened, I would place the abduction event somewhere after the first or second flash. After that my memory becomes hazy, but I am positive I was in the car because I distinctly remember having a repeated conversation with my friend. We both experienced a deja vu that lasted for 4-6 minutes, followed by a period of mild consciencness and hazy memory. Our conversation, the music we were listening to, and the series of events we discussed were a conversation my friend and I had a few weeks earlier Verbatim. If anybody can tell me anything about what possibily happened to me last night I would greatly appreciate it. I'm not terribly concerned but I'm interested in what happened to me because it was not normal. Any person to talk to about this would be a help for me.
