Meaning of this dream?

. So I had a dream my house was filling up with carbon monoxide and my family and friends were not responding so I had to carry them all out one by one. I finally got out and then a swarm of black and grey birds attacked me and I was laying on the ground crying and panicking. This has been reoccurring for the past couple of nights. I think I know what is means.. But what do you guys think?
