Both pines (Genus: Pinus) and cypress (Family: Cupressaceae) do have leaves.
Pines have four types of leaf:
Seed leaves (cotyledons) on seedlings, borne in a whorl of 4–24.
Juvenile leaves, which follow immediately on seedlings and young plants, 2–6 cm long, single, green or often blue-green, and arranged spirally on the shoot. These are produced for six months to five years, rarely longer.
Scale leaves, similar to bud scales, small, brown and non-photosynthetic, and arranged spirally like the juvenile leaves.
Needles, the adult leaves, which are green (photosynthetic), bundled in clusters (fascicles) of 1–6, commonly 2–5, needles together, each fascicle produced from a small bud on a dwarf shoot in the axil of a scale leaf. These bud scales often remain on the fascicle as a basal sheath. The needles persist for 1.5–40 years, depending on species. If a shoot is damaged (e.g. eaten by an animal), the needle fascicles just below the damage will generate a bud which can then replace the lost leaves.
Cupressaceae, the cypress family (order Pinales), 30 genera with 133 species of evergreen ornamental and timber shrubs and trees, distributed throughout the world. The leaves of these plants are opposite or whorled and usually paired or in threes. Adult leaves are narrow, scalelike, and pressed against the branchlets, which themselves are often flattened. Awllike juvenile and transitional leaves are often present on mature trees. The male reproductive structures are borne at the ends of short twigs; the female structures (cones) are terminal, with opposite or whorled scales, consisting of both a fused bract (modified leaf) and a scale. The cones, usually woody, have erect ovules.
I guess I never really considered leaves and needles the same thing. But technically, pine needles fit the definition of a leaf and are classed as such. I learned something today. "Leaf" has a really broad definition. But I don't typically hear people refering to the foliage of conifers as leaves.
And thanks for the copy and paste. But could you have explained this in your own words?
Is it normal that i extremely fear pine trees?

I do not think that I could've explained it better, but please see my comment below, under 'Avant-Garde."

That's a shame.
