Red Thread, welcome.

Just a bit of advice from my own experiences: If, during whatever type of meditation you're doing, a particular subject or theme arises, that's your subconscious at work. If it's death, then that's what your mind needs to deal with at this time in order to restore balance to your being. So, instead of worrying about it or letting it stress you, go with it. Meditate on death. There are numerous descriptions in the Pali Canon on death meditation.

For example, visualize a fresh corpse, a corpse a few days old, a few weeks old, etc, with a mind towards peaceful acceptance of the inevitability of death. Become disillusioned, in the literal sense, with life, yours or others'. Detach from the view of yourself as an enduring entity. Death will come to every living thing. What's to do about it? Nothing you do can change the inevitability of death, so the only thing left for benevolent beings is to try to affect more peace and less suffering for our fellow ephemeral beings in the present and future. After you let go of life can you really begin to live more deeply. I'm not talking about transcendent ideals; I'm just saying that there's not much else worthwhile for a benevolent being to do. Someone will one day bury your children, too, won't they?

Nothing new came into being at birth, nothing ceases to be at death. There's no way to lose, no reason to grieve.
