Does anyone else remember these children's cassette tapes?

-It was a set of cassette tapes made for kids to play while falling asleep. They were of a man telling stories. I remember these as several of the cassette stories:



1: About finding a unicorn in a meadow (I think) and I think at one point the story point of view was riding the unicorn through a valley or something.



2: In the middle of the summer in a tree house located right in the middle of a peach (I think it was a peach) orchard. I remember the narrator describing the crickets.



3: A toy shop. All the toys came alive in the shop and were doing some sort of mission, though I don't remember exactly what it was.



4: I'm not sure if this is one or not, but I vaguely remember some modern house with a square pool in the middle of a red hot desert. But this could have just been my imagination going off.



These tapes were from a long, long time ago. I had them when I was young in the 90's, but I have a feeling they maybe were from the later 80's as well from when my sister was younger.



Does anyone know what these tapes are called?! Someone mentioned the memory of them to me today, and the thought is just under my skin now... I can't for the life of me remember what these children tapes are called!
