Can a habitable world exist that would orbit in and out of a nebula?

Not an astronomer (obviously), but had a curious question. Is it possible to have a planet such that:

• Its star is right on the edge of a nebula

• The planet happen to be in the goldilocks zone and has the right atmospheric makeup to support life

• This planet's orbit takes it in an out of the nebula, creating a "Nebula Season"
• This season is observed by its inhabitants by the sudden lack of visible celestial bodies in the sky (due to the nebula. Can be gradual but should be a notable difference between June and December, for instance). Perhaps like the effects described in: What would skies look like on Worlds inside Nebulae?

Is this scenario possible? Can such a star system exist in such a location? and Bonus: Can the Nebula be dense enough to produce the mentioned effect?

I'd be happy if you'd correct my assumptions!
