pigeons

There's been several pigeons visiting my balcony over the past few days. They arrive first thing in the morning at 6am onward and wake me up with the pigeon sounds (I won't attempt to try and spell out the sound, just imagine it). I dream a lot, especially in the morning, so for the past few mornings I keep hearing the pigeon sound in my dreams and wonder, 'what the heck is that sound??'. I don't see the pigeons in my dreams, I just end up wandering around and looking around everywhere as the scenery changes but can't figure out what that sound is...until I wake up...walk over to the balcony and clap my hands to shoo away the pigeons. They're cute and all, but I don't want them to be hanging out there every morning or eventually building a nest there because they're comfortable, so I have to 'scare' them away in a way :P
