Dream of chased, female, number

I dreamt a small innocent looking man in his 60s was catching a female mute swan to be taken somewhere. He put her in the back of a delivery van (in this case, frozen chips/fries) but it was empty. As he put her in he threw her because she tried to defend herself and then I witnessed him throwing a large heavy roll of paper at her and shouting You S.O.B... The make swan was calling for her (with the voice of a stag) from the public park where they lived. The man disappeared but I had taken down the number on van to report. He returned and i somehow got in the van and rescued the swan who was all bound up and strung up like a trophy. The man said he was going to kill both of us but I got her out and released her back into her habitat. He found out and chased me, but then I found his van all boarded up in an attempt to hid his identity. I ripped it all off to show people who he was.
