Yes. This happens to me, my dad died 3 months ago. I asked around when it first happened and it seems like it is a normal thing. Usually my dad is randomly in my dream and there is nothing remarkable about it. I just think hey there's dad and that is that. If it is upsetting you then maybe you should see if you can talk to someone about it, but otherwise it is perfectly healthy and natural.

On rare occasions.
It does happen.I hope those feelings bring you peace and comfort.

Yes, I had a dream like that with my dad & his brother (my Uncle). My dad's brother died around 1985. My dad died in 2005.
The dream started with a "old" car (one with wing shaped fenders; like a picture of my dad's car). The car is right in front of me & my friend who has been there helping me though this tough time; my mom's death in 2007. The next thing that happend is my dad steps out of the drivers side; and opens the door of the passenger side door (my dad always opened the door for my mom). I get in first, and slide over. My friend then gets in. I didn't really look out the window of the car ( I wish I had)...I may have glanced out and couldn't see anything...I don't remember. What I do remember is...noticing that someone "familiar"...was sitting in the front passenger side. I looked and saw that it was my Uncle! When my Uncle was alive he and I would sit and play checkers; when he got Parkinsons and we visited him at his house (with his then second wife..not the nicest; I would sit with him & talk. I loved him soooooo much.
Any way....I noticed my uncle and I stood up the best I could and hung over the front seat so that I could give him a hug. I had placed my arms around him, and one of my palms landed on his chest...when it did...I felt his heart beat!!!!!! I woke up with a sense that I had been there. It made/makes me feel "good" to go back and remember that.
I have read/ and do read...Sylvia Brown books.

No.It doesn't upset me.It doesn't happen often.It just happens once in awhile.It's like he's letting me know he's ok.
