It would appear your secondary is out of alignment. There dot should be hitting the centre of the primary centre spot. Do that first.
Suggest you download Astro baby's collimation guide.
PS details of your scope would help us help, like f ratio. Secondary offset varies slightly by f ratio in newts (Dobs). I suggest you check that all your struts are at maximum travel and locked in place, a schewed top section can offset the beam too.
