Perplexed over this very emotional dream

Last night I had one of the most emotional dreams I think I have ever had.

Not quite sure how it had begun but I had heard some news about dogs that were being put down totally unnecessarily. Anyway I was walking down the street with I think a stranger and our walk took us near to the place these dogs were being put down. The first I realised was when I started seeing all these people carrying their pet dogs in the same direction and the dogs we're struggling to get away. When I realised where we were I felt very distressed and just couldn't believe these people were all taking their pets there.

Then my dream switched to later on in the day when all these beautiful dogs had already been put down. I was so distraught and angry. All these same people were gathered and having almost a party - not really celebrating, just gathering together and playing back videos of when their pets were alive - sort of augmented reality where they could see the street before them on their camera phone but play an video of their pet and it almost looked like it was back alive again on the street. I started approaching these people and asking them angrily why they had put their dogs down (which wasnt in the normal way, more like killing them by getting them to smell a lethal medicine or something). I even commented that normally I wouldn't confront people when i disagreed with something (this is true to real life) but because I was so angry I lost all my reserve. Most were annoyed at being confronted but about 20% agreed with me but It almost seemed as if they had been brainwashed into doing it.

The third part of this dream is a bit more vague, but it was the very end of the day and I was possible floating around the streets or maybe I was being driven though it did seem to be from a bit of an elevated view and I saw a few of the doggies floating upwards and they had angel wings. I was vaguely aware that no one else could see them. It made me a little happier to realise they were still around.

Sometime after I awoke from this dream I had a sort of a feeling that I had been given this dream from the afterlife (at the time I was staying at a hotel with my husband and it seemed connected with this hotel). But it was a brief feeling before I fell back to sleep again. When I woke up again this morning and told my husband about it I found myself in floods of tears! That is the emotional impact it had on me.

Can anyone help me in figuring this out, Im usually ok with interpreting my own dreams but Im completely stumped with this one. Only thiing I can say is that recently I have been wondering about the afterlife a bit - not about my own immortality, just more about if spirits exist. Oh and recenly a few people have jumped in front of a train in our neighbourhood - maybe the dogs are actually referring to those people. I do find it incredibly sad that someones beloved son, daughter or family member would do this leaving their distraught family to try and come to terms with the whole tragedy.
