Ride With Unknown

This is my first post on this site (And I hope last one as well, because I don't want to experience anything like it again). I found this site while searching an answer to my questions. Before I start with my story I would like to tell you some details about it so you can get a clear picture what had happened.

I am a 25 year old guy. Before this I can't really say that I had any paranormal experience. That doesn't mean that I haven't felt anything like that, but it didn't have any proof that the actions were paranormal so I ignored them. I am not a very religious person but yes I do believe in God.

Now, let's get back to the story. This happened 2 weeks ago. It wasn't very late in the night. I was doing afternoon shift and left the office around 23 30. I took out my bike from parking and started heading towards my room (I stay in rented house as I work away from my home town). It is exactly 7 KM (I don't know in miles as we don't use it much in my country) from my office, so it hardly takes 10-15 minutes to reach home. The road which I take to go home is quite a normal one; it's not a lonely or horrifying kind of a road. And as mentioned earlier it wasn't very late at night, but this night was bit strange because normally if you go by that road and even if it's after midnight you will find other cars and bikes passing by you. But this time there wasn't any car or bike you can see within a sight. I didn't pay much attention to it and continued my journey. I took a turn and started a very short (maximum 2 mins) lonely patch which comes in between. Everything was looking perfectly fine, street light were proper even the moon light was very bright but I felt like that short patch has become very long. But still I didn't worry much about it as I thought it's my imagination.

Suddenly I saw an old man standing beside the road and waving his hand for lift. I thought it would be a very wise thing to help an old chap so I stopped the bike in front of him. But as soon as I stopped the bike he started looking at me very strangely. Still I asked him "Can I drop you somewhere, Sir?" He said "Yes. I want to go to the next corner but why did you stop?" I was bit surprised by that question. I said "I'll drop you there". Old man replied "How three of us can sit on the bike?" and he was looking at the back seat of my bike. I felt little confused and freaked out. I turned my head to look at my back seat. There wasn't anybody on the backseat but it was pressed little bit down as if someone was sitting on it. After looking at that I got completely freaked out. I looked at the old man he was very calm and as if nothing wrong in the current situation. I didn't know what to say or what to do. If somebody is sitting behind you on a bike, you will at least feel some presence? But until the old man notified me I didn't feel anything. And just to clarify that my bike is not second hand one. I purchased a brand new bike just six months ago. I haven't met any accident or any other bad thing during this period to justify this situation.

Unknown what to do, I looked at old man and started my bike to continue. As soon as I started riding I felt like someone is putting arms around my stomach. Now this scared the hell out of me and my complete body started sweating. But still I continued, because even though my parents don't believe in all this things my grandmother does and she told me numerous stories of her encounters with ghosts (or we can say spirits, I don't know exactly). When she used to tell me the stories, she always mentioned one thing that, have faith in God and yourself as well. I kept that in mind and started riding as fast as I can. Because just after that patch there is one temple of lord Ganesha and I wanted to reach there as early as possible. The grip around my stomach wasn't a very hard or hurting rather it was a very soft grip but as I started to increase my speed it started holding me tighter. (So I didn't really know what it was and why it chose me?)

Finally I reached near temple and I stopped. I couldn't dare to get off the bike as the grip was still there. I waited there for 2-3 minutes but nothing was changing, the grip was still on me. But after waiting there I was pretty sure that whatever it is, it's not going to harm me. So I started the bike again and continued, I was still pretty scared and sweating. After that I reached home within next 3-4 minutes I live with five other mates in row house (it's a big one) and we have our own parking. I entered the parking. One of my mates was sitting in the hall watching TV and the entrance door was wide open from where he saw me. I was still sitting on the bike as the grip was still there. My friend looked at me and shouted from hall itself, "Hey! What are you doing? Come inside" As soon as he shouted the grip was gone. I turned back and looked at the seat, it was normal. I parked the bike and went inside the room and closed the door. I didn't dare to tell anyone about it.

But while all this was happening, for single moment I didn't feel like something bad is going to happen with me. But of course I was scared a lot because of grip and all. And one more thing which bothered me that, if the old man could see that someone was sitting behind me then why couldn't my friend? And why all this happened with me? Because I don't have any history, any connection with this particular area or people around it which can explain this. I am still using the same road after this incident to travel, but nothing has happened. After thinking with all the aspects on what had happened I am not scared anymore but I also don't want it again.

Any suggestions for preventing it from happening again are most welcome. And any comments which to answer the questions in my mind are also most welcome.

Sorry for the length.
