In my dreams I have always had one recurring common denominator, in that whoever I am with keeps changing, from one person to another, i dont physical see them change, one minute im with person A as we walk down the road chatting, then when I look over to person A its changed into person B!

Last night i dream i was on holiday somewhere spanish or greek with my wife and three boys, we were in a hotel restaurant. the restaurant seemed to be about halfway up the building, it was a relaxed atmosphere, music, happy people etc.
As usual one minute im sitting with my family the next im with some friends at this hotel, then im walking back to our room with one of my kids, the next minute we are all walking down a hotel corridor.

After walking sometime I noticed a big rocking motion i guess like an earth quake or bomb, the building was swaying and were inside. I knew we had to get out, (my dreams often jump from one scene to another) next im outside with my eldest son who is in a real panic asking for his mum, at this point everyone we know has gone its just him and me.
we dont know where the building is as we are in the busy street with buildings everywhere, so we go walking trying to find them, in the background whilst walking we can here people say it was terrorist attack and others saying a helicopter hit the building.
eventually we find the building which is collapsed, as i go nearer to the building i see an overturned car, as i approach the car i notice my youngest son is trapped inside, i get him out the car (that was a 'people transition', one minute i was with my eldest son, now im with my youngest).

my youngest son and i approach the collapsed building to look for the rest of my family and go through a dark tight tunnel, once we are inside my son says he know where mums room is, yet we cant find it, the searching went on for sometime, again the people searching with me came and went, always someone different.
and then i awoke, all very odd!
also I remember having to tell my son a one point that everyone is dead!

I think it's normal for people to change in dreams. That happens in my dreams.

It's probably because the people in your dreams represent qualities, and different people in your life can represent the same qualities - to your unconsious mind they're all the same.

For example, your family and your friends can all represent the desire to have close relationships with other people, the need to be around people you feel safe with, etc.

Dreaming that you are on holiday could mean that you need a change in your life.

Since you are in a restaurant, you could feel that you need some attention from others and some "nourishment " - you want someone else to give you something rather than you always giving to others.

The bomb could have to do with what you think could be the negative consequences of making a change so that you don't have to do so much for other people.

How old are your sons? If your sons are quite young, then the younger son would need more care and attention from you than the older son. The dream could have to do with your thoughts about how much attention your children need from you.
