I was coming back from a ride on my motorcycle (road cruiser), headed home there is a long street called ashley street, very straight road about 2km long. i was on ashley st casualty riding when i realised no one else was on the road infront or behind me which i thought was odd as it is a popular road and usually quite busy that time of day. i decided to slow down a bit and enjoy the ride (no traffic). i suddenly felt compelled to look up and towards the sky to my right (south west) the sun was not long past its zenith so i got a clear look at this thing. i initially thought it was a silver balloon i noticed it when i was exactly adjacent to the object about 35 meters away and roughly 35 maybe 40 meters in the air. still riding i did a double take as it had not moved in terms of floated higher, or drifted away out to the gulf. i dont know why but i slowed down but did not stop to keep looking at this thing. i then started to think drone or rc balloon. still looking (my speed now 50kmp) it seemed to dance up and down only a few feet and started to morph shape from a solid oval, to a perfect spear then to what i could describe as a tear drop (horizontally) then repeated this vertically and horizontally again (the shape changing) all the while not moving more than a few feet up or down left or right. i returned my eyes to the road and rounded the corner onto mimosa st and pulled over to scan the sky in the direction i saw the object, gone. my initially feels were a deep sense of curiosity then when it started to change shape i became giggly? this "funny" feeling left within seconds then i had an overwhelming sense of safety/security about me, i can best describe this feeling like when you're a young child and you're drifting off to sleep on the couch with father sitting next to you, sort of like a confident "everythings going to be okay" feeling. i still have my doubts but what makes me think it was an ufo be it alien or government was the timing and the odd emotions i experienced.
